Experimental And Theoretical Study On Condensation Heat Transfer Of Nonazeotropic Refrigerant Mixtures R1234yf/R32 Inside A Horizontal Smooth Tube, Linlin Wang, Chaobin Dang, Eiji Hihara Jan 2012

Experimental And Theoretical Study On Condensation Heat Transfer Of Nonazeotropic Refrigerant Mixtures R1234yf/R32 Inside A Horizontal Smooth Tube, Linlin Wang, Chaobin Dang, Eiji Hihara

International Refrigeration and Air Conditioning Conference

The condensation heat transfer characteristics of nonazeotropic mixtures R1234yf and R32 (mass fractions of 0.52:0.48 and 0.77:0.23, respectively) inside a horizontal smooth tube (inner diameter 4 mm) were experimentally studied at mass fluxes ranging from 100 to 300 kg/m2 s. A prediction model for the forced convective condensation heat transfer characteristics of nonazeotropic refrigerant mixtures was also constructed based on the measured results, and the details are presented. The heat transfer characteristics, especially the heat transfer deterioration of the nonazeotropic refrigerant mixture, are evaluated by combining the correlations of heat transfer and mass transfer at both the vapor side and …

Numerical Simulation Of Two-Phase Flow Pattern Of Supercritical Carbon Dioxide With Pag-Type Lubricating Oil In Gas Cooler, Chaobin Dang, Shintaro Arai, Eiji Hihara Jan 2012

Numerical Simulation Of Two-Phase Flow Pattern Of Supercritical Carbon Dioxide With Pag-Type Lubricating Oil In Gas Cooler, Chaobin Dang, Shintaro Arai, Eiji Hihara

International Refrigeration and Air Conditioning Conference

It has been reported that lubricating oil has a significant influence on the cooling heat transfer of supercritical carbon dioxide. In this study, numerical analysis of the flow pattern of a carbon dioxide (CO2)-oil mixture in a gas cooler was conducted to analyze the change in oil film thickness and heat transfer coefficient against bulk temperature. Simulations were conducted using FLUENT software, and the volume-of-fluid (VOF) model was applied to capture the interface of the lubricating oil and CO2. The compatibility of lubricants was found to have a dramatic influence on cooling heat transfer. The flow regime changes due to …

Study On Ejector - Vapor Compression Hybrid Air Conditioning System Using Solar Energy, Chaobin Dang, Yoshitaka Nakamura, Eiji Hihara Jan 2012

Study On Ejector - Vapor Compression Hybrid Air Conditioning System Using Solar Energy, Chaobin Dang, Yoshitaka Nakamura, Eiji Hihara

International Refrigeration and Air Conditioning Conference

The ejector cycle has been recognized as a promising cycle for the utilization of solar energy for cooling. However, the conventional ejector cycle suffers from low efficiency owing to a low evaporation temperature. This paper proposes a hybrid ejector-vapor compression heat pump cycle. This hybrid system uses an ejector cycle on the hightemperature side and a conventional vapor compression cycle on the low-temperature side to enhance the cycle performance of a solar-powered air conditioner. A cycle simulation showed that the proposed hybrid ejector cycle could operate during both the heating and cooling seasons and would provide energy savings. In heating …

Study On Annual Performance Of Room Air Conditioners Under Partial Load Condition, Hayato Horie, Eiji Hihara Jan 2012

Study On Annual Performance Of Room Air Conditioners Under Partial Load Condition, Hayato Horie, Eiji Hihara

International Refrigeration and Air Conditioning Conference

Because of the moderate climate of Japan, most of the air conditioners (A/Cs) used are split-type A/Cs and can provide both heating and cooling during the year. Therefore, the coefficient of performance (COP) and the annual performance factor (APF) are used as criteria to evaluate the annual average performance of A/Cs; these criteria are established on the basis of Japanese Industrial Standards (JIS). The JIS-based performance rating method is easy and useful but does not take into account the intermittently driven mode of the compressor. In practice, A/Cs are mainly operated under partial load conditions, which are often 30%–50% of …

The Ecology Of Parafluvial Ponds On A Salmon River, Zachary Jon Crete Jan 2012

The Ecology Of Parafluvial Ponds On A Salmon River, Zachary Jon Crete

Graduate Student Theses, Dissertations, & Professional Papers

Parafluvial ponds are discrete lentic habitats embedded in the alluvia of gravel bed rivers that are formed by flooding and persist in relation to floodplain geohydrology. On the expansive flood plains of the Kwethluk River, I observed thousands of juvenile salmon apparently trapped by surface disconnection of the ponds from the river. I was interested in whether the salmon could survive until flooding reconnected the ponds to the river. I sampled ponds along the river corridor to describe habitat quantity and juvenile salmon presence, growth, and diet. Furthermore, I looked at pond hydrology, temperature regime, and the role groundwater plays …

Transnational Conservation Contracts, Natasha Affolder Jan 2012

Transnational Conservation Contracts, Natasha Affolder

All Faculty Publications

Transnational environmental law is the subject of growing scholarly interest. Yet, much work remains to be done to fill in both the conceptual and empirical contours of this field. One methodological challenge that transnational law poses is the need to look beyond traditional sources of international and national law. This article contributes to efforts to understand transnational law's multilayered architecture by drawing attention to the use of transnational contracts as a mechanism to protect habitats and species. The diverse and proliferating examples of conservation contracts discussed in this article – which include forest carbon agreements, conservation concessions, debt-for-nature swaps, conservation …

Relationship Between Log Permeability And Fraction Of Finer Grains In Bimodal Sediment Mixtures, Steven M. Verdibello Jan 2012

Relationship Between Log Permeability And Fraction Of Finer Grains In Bimodal Sediment Mixtures, Steven M. Verdibello

Browse all Theses and Dissertations

In sediment mixtures of two grain-size components, the mixture porosity (Φ) and permeability (k) both vary non-linearly as a function of the grain size and the volume fraction of each component. A porosity minimum (Φmin) occurs near the mixture fraction at which the volume of the finer grains equals the original pore volume of the coarser grains. An abrupt change in slope has been observed in the non-linear relationship between log(k) and the volume fraction of finer grains (rf). This slope change should occur at the rf where coarser pore pathways change from continuous to discontinuous. In this study, fine …

Degradation Of Chlorinated Hydrocarbons In Groundwater Passing Through The Treatment Wetland At Wright-Patterson Air Force Base: Analysis Of Results Collected During 2001-'06, Annamarie F. Therrien

Browse all Theses and Dissertations

Constructed wetlands are an efficient and cost effective means for chlorinated aliphatic hydrocarbon remediation, and will therefore continue to gain momentum as an accepted treatment by the US EPA (U.S. EPA, 1995; Amarante, 2000; Lien, 2001; WETPOL, 2009). The treatment options for chlorinated aliphatic hydrocarbons (CAHs), including wetlands, capitalize on aerobic/anaerobic interfaces in which bacterially mediated reduction-oxidation reactions degrade pollutants (Li, 1997; Bradley, 1998; Lorah and Voytek, 2004; Amon, 2007; Imfeld, 2008). In August 2000, researchers at Wright State University (WSU) combined efforts with the United States Air Force Institute of Technology (AFIT) to construct a pilot-scale upward-flow treatment wetland …

Investigations Into The Role Of Natural Organic Matter As An Interface Between Aquatic Organisms And Environmental Pollutants, Caroline Lillian Schneider Jan 2012

Investigations Into The Role Of Natural Organic Matter As An Interface Between Aquatic Organisms And Environmental Pollutants, Caroline Lillian Schneider

LSU Doctoral Dissertations

The impact of the continuous pollution of freshwater environments by multiple pollutants has not been well-studied. The goal of this research was to evaluate the toxicity of several modern pollutants in a model environment. The prokaryotic, unicellular blue-green algae Synechocystis WT6803 and the eukaryotic, multicellular Utterbackia imbecillis mussel larvae were studied along with Suwannee River natural organic matter (NOM). The toxicity response of the blue-green algae Synechocystis sp. was measured through changes in growth rates. The inorganic pollutant silver nanoparticles (0.044 μM) were toxic. Gold nanoparticles did not affect the growth rate. The addition of 15 mg/L NOM partially inhibited …

Landscaping Perceptions And Behaviors: Socio-Ecological Drivers Of Nitrogen In The Residential Landscape, Leesa Souto Jan 2012

Landscaping Perceptions And Behaviors: Socio-Ecological Drivers Of Nitrogen In The Residential Landscape, Leesa Souto

Electronic Theses and Dissertations

Driven by individual influences such as beliefs, attitudes, personal norms, and abilities, as well as by social influences like community norms, mandates, and the market, suburban homeowners are motivated to select and maintain a turf grass landscape. In many areas of Florida, effective suburban lawn maintenance requires regular inputs of nitrogenous fertilizer, some of which is lost to the environment, contributing to water quality degradation and ecosystem dysfunction. Reducing nitrogen inputs to aquatic systems requires a better understanding of the links between residential landscape management and the potential for fertilizer loss. This dissertation examines the linkages between the human behaviors …

Assessing Urban Environmental Management Practice With A Scalar Approach: The Case Of Shanghai, Wei Tu Jan 2012

Assessing Urban Environmental Management Practice With A Scalar Approach: The Case Of Shanghai, Wei Tu

Earth, Environment & Sustainability: Faculty Publications

Shanghai’s urban environmental management in the past three decades has been focused primarily on the environmental problems at the intra-urban level. While this ‘end of pipe’ approach greatly mitigated domestic and industrial pollution, progresses were much slower in dealing with environmental impacts both at a smaller (i.e., those related to people’s daily activities) scale and at a larger (i.e., those related to inter-urban/regional or global issues) scale. Urban environmental management policies in Shanghai and China should prioritize and address urban environmental impacts at continuous geographic scales to achieve long-term ‘triple bottom line’ sustainability.

The Value Of Marine Conservation, Sian Rees Jan 2012

The Value Of Marine Conservation, Sian Rees

Other Faculty of Science and Engineering Theses

The marine environment provides essential ecosystem services that are critical to the functioning of the earth’s life support system and the maintenance of human well-being. Marine Protected Areas (MPAs) are recognised as being the mechanism though which marine natural capital may be conserved. This thesis focuses on the value associated with marine conservation in a case study area, Lyme Bay, England where a ‘closed area’ was created in 2008. A review of literature spanning 20 years shows that despite sound ecological knowledge of a marine area, the reliance on traditional neo-classical economic valuations for marine spatial planning can obscure other …

Evaluation Of Shoreline Change Using Optical Satellite Images, Case Study Of Progreso, Yucatán, Gabriela Garcia-Rubio Jan 2012

Evaluation Of Shoreline Change Using Optical Satellite Images, Case Study Of Progreso, Yucatán, Gabriela Garcia-Rubio

Other Faculty of Science and Engineering Theses

A technique to extract the shoreline from optical satellite images has been developed, evaluated and applied to the case study site of Progreso, Yucatán, México. This site was chosen as it is frequently subject to hurricanes, shows shoreline erosion and has a paucity of coastal data. The area under investigation is an 8 km length of shoreline that faces north into the Gulf of México. A novel method to extract satellite-derived shorelines (SDS) was developed ensuring the maximum contrast between sea and land. The SDS was validated using quasisimultaneous in situ shoreline measurements from one day in two different years …

Land Use For Energy Conservation And Sustainable Development: A New Path Toward Climate Change Mitigation, John R. Nolon Jan 2012

Land Use For Energy Conservation And Sustainable Development: A New Path Toward Climate Change Mitigation, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

Land use tools and techniques have impressive potential to reduce energy consumption, improve the economy, and mitigate climate change. This article explores the little understood influence of local land use decision-making on energy conservation and sustainable development and how it can mitigate climate change if properly assisted by the federal and state governments. The construction and use of buildings combined with extensive vehicular travel throughout the nation’s human settlements consume large amounts of energy, and much of that consumption is highly inefficient. By enforcing and enhancing energy codes, encouraging the use of combined heat and power and district energy systems, …

Potential Wolverine Habitat Vs. Winter Recreation. Conflict In Colorado!, Paul Quigley

Geography and the Environment: Graduate Student Capstones

The Global list of endangered species of flora and fauna is growing, with the most highly specialized species often at ‘critically endangered’ status. Managing these populations effectively involves numerous and varied organizations, conflicting motivations, arbitrary anthropogenic boundaries and often most importantly, data compilation and management. We are seeing many more reintroductions of locally extirpated species back into habitats of historical prevalence – and as extreme a method of conservation as this is, there is still a need for more extreme methods. High profile and highly specialized endangered species are often managed in a ‘crisis’ mode, where complex behaviors and interactions …

The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz Jan 2012

The Geography Of Greenhouse Gas Emissions From Within Urban Areas Of Asia, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz

Publications and Research

This paper aims to advance two objectives: (1) identify and explore greenhouse gas emissions from urban areas in Asia at the regional level; and (2) explore covariates of urban greenhouse gas emissions. We use the Emissions Database for Global Atmospheric Research estimates for carbon dioxide, methane, nitrous oxide, and sulfur hexafluoride from 14 source activities for the year 2000, which are allocated on a 1/108 global grid. We extract emissions for 3535 urban extents all with populations over 50,000, accounting for approximately 91% of the region’s urban population. We use regression analysis to associate emissions with urban area and growth, …

OES Faculty Publications

Marine N2 fixing microorganisms, termed di-azotrophs, are a key functional group in marine pelagic ecosystems. The biological fixation of dinitrogen (N2) to bioavailable nitrogen provides an important new source of nitrogen for pelagic marine ecosystems and influences primary productivity and organic matter export to the deep ocean. As one of a series of efforts to collect biomass and rates specific to different phytoplankton functional groups, we have constructed a database on diazotrophic organisms in the global pelagic upper ocean by compiling about 12 000 direct field measurements of cyanobacterial diazotroph abundances (based on microscopic cell counts or …

How Milk Does The World Good: Vernacular Sustainability And Alternative Food Systems In Post-Socialist Europe, Diana Mincyte Jan 2012

How Milk Does The World Good: Vernacular Sustainability And Alternative Food Systems In Post-Socialist Europe, Diana Mincyte

Publications and Research

Scholarly debates on sustainable consumption have generally overlooked alternative agro-food networks in the economies outside of Western Europe and North America. Building on practice-based theories, this article focuses on informal raw milk markets in post-socialist Lithuania to examine how such alternative systems emerge and operate in the changing political, social, and economic contexts. It makes two contributions to the scholarship on sustainable consumption. In considering semi-subsistence practices and poverty-driven consumption, this article argues for a richer, more critical, and inclusive theory of sustainability that takes into consideration vernacular forms of exchange and approaches poor consumers as subjects of global history. …

A New Method To Derive Electronegativity From Resonant Inelastic X-Ray Scattering, Stephane Carniato, Loic Journel, Renaud Guillemin, Maria Novella Piancastelli, Wayne C. Stolte, Dennis W. Lindle, Marc Simon Jan 2012

A New Method To Derive Electronegativity From Resonant Inelastic X-Ray Scattering, Stephane Carniato, Loic Journel, Renaud Guillemin, Maria Novella Piancastelli, Wayne C. Stolte, Dennis W. Lindle, Marc Simon

Chemistry and Biochemistry Faculty Research

Electronegativity is a well-known property of atoms and substituent groups. Because there is no direct way to measure it, establishing a useful scale for electronegativity often entails correlating it to another chemical parameter; a wide variety of methods have been proposed over the past 80 years to do just that. This work reports a new approach that connects electronegativity to a spectroscopic parameter derived from resonant inelastic x-ray scattering. The new method is demonstrated using a series of chlorine-containing compounds, focusing on the Cl 2p−1LUMO1 electronic states reached after Cl 1s→LUMO core excitation and subsequent KL radiative decay. Based on …

Resonant Inelastic X-Ray Scattering Of Methyl Chloride At The Chlorine K Edge, L. El Khoury, Loic Journel, Renaud Guillemin, Stephane Carniato, Wayne C. Stolte, T. Marin, Dennis W. Lindle, Marc Simon

Chemistry and Biochemistry Faculty Research

We present a combined experimental and theoretical study of isolated CH3Cl molecules using resonant inelastic x-ray scattering (RIXS). The high-resolution spectra allow extraction of information about nuclear dynamics in the core-excited molecule. Polarization-resolved RIXS spectra exhibit linear dichroism in the spin-orbit intensities, a result interpreted as due to chemical environment and singlet-triplet exchange in the molecular core levels. From analysis of the polarization-resolved data, Cl 2px, y and 2pz electronic populations can be determined.

"Near-By Nature": A Logical Framework For Building Integrated Agriculture., William Plyler Jan 2012

"Near-By Nature": A Logical Framework For Building Integrated Agriculture., William Plyler

Graduate Theses, Dissertations, and Problem Reports (ETD)

Building Integrated Agriculture (BIA) aims to reduce the environmental footprint of food production and to improve the human condition. BIA places food producing plants into the everyday working/living environment. This study explored the intersection of the diverse BIA requirements (human, plant, and building) as established by the relevant literature from various disciplines. Kaplan (1992), and Ulrich (1984; 1986; 1992) established the restorative physiological and psychological effects of plants in non-natural settings. Kaplan deemed these settings “Near-by Nature.” In building interiors, “Near-by Nature” is achieved through interiorscaping, a design practice that incorporates plant, building and occupant requirements. This study specifically investigated …

Diagnosing Institutional Fit: A Formal Perspective, Michael Cox Jan 2012

Diagnosing Institutional Fit: A Formal Perspective, Michael Cox

Dartmouth Scholarship

I attempt to demonstrate that the concept of institutional fit and the closely related approach of institutional diagnosis can be improved with the process of formalization. In this context, the concept of fit is interpreted as a way of expressing certain theoretical propositions that relate a set of variables with each other and with an outcome. This perspective is demonstrated through the use of the Web Ontology Language to express several "theories of fit." Using a formal language to describe types of fit and their associated theories is argued to have much potential for advancing the scientific study of social-ecological …
