Small Scale Wind Turbine, Cameron Allen, Davis Gumbo, Mitchell Petronek, Scott Roskens

College of Engineering Presentations

The Department of Energy (DOE) has put together a collegiate wind competition to design, build, and market a small wind turbine (17.7in diameter rotor dimension). For our mechanical engineering senior design project our team will participate in this competition. Ten schools will compete in the competition in Las Vegas this May. Our team designed a wind turbine to produce power for ultraviolet light water purification in remote areas and during emergency situations. The turbine was designed to produce 10 watts at a wind speed between 5 and 14 m/s. The turbine is also equipped with an emergency brake that will …

Simulation Of An Intake Manifold Pre-Heater For Cold Diesel Engine Startup, Patrick K. Kreun

Masters Theses

Ensuring consistent, reliable diesel engine startups in cold temperatures is of utmost importance in a number of applications. Under extreme temperatures, the use of glow plugs is complemented by intake manifold heaters. In these, the energy released from combustion increases the intake air temperature before the air enters the main combustion chamber. Since the process also alters the stoichiometry of the fuel-air mixture at the intake ports, the preheater operation must be optimized in order to guarantee successful and reliable in-cylinder combustion during engine startups. This paper describes the development of an intake manifold model incorporating an air pre-heater for …

A One-Dimensional Model Of A Closed-Loop Refrigeration Test Block For Centrifugal Compressors, Paul D. Gessler

Master's Theses (2009 -)

The increasingly competitive building equipment and control industry pushes manufacturers to continually improve the performance and efficiency of their products to develop and maintain a competitive edge. Compressor development is an expensive endeavor, but the cost and time required for testing can be minimized by developing a model of the compressor test block to predict its behavior with a given prototype compressor at specified operating conditions. This thesis presents a thermodynamic model of a hot gas bypass test block used to evaluate centrifugal compressor performance at a compressor development facility. The test block uses cooling towers to reject the heat …

A Metaevaluation Of Energy Efficiency Evaluations, Brandy Brown

Dissertations

This study systematically reviews the methodological characteristics of energy efficiency evaluations and uses metaevaluation to assess its quality. Metaevaluation is used to systematically assess the quality of evaluation products, confirm that evaluations deliver sound findings and conclusions, are useful to the client, are credible, are ethically conducted, and are done as cost-effective as possible. The results of this study show that the ability to accurately assess evaluation for methodological quality using evaluations reports as a primary data source depends on the presence of detailed descriptions of evaluation methods. Furthermore, the study suggests that methodological variations of energy efficiency evaluations coalesce …

Modeling And Experimental Investigation Of Parabolic Trough Solar Collector, Mohanad Abdulazeez Abdulraheem Alfellag

Doctoral Dissertations and Master's Theses

In this thesis, a mathematical model is applied to study the performance of a parabolic trough solar collector (PTSC). The proposed model consists of three parts. The first part is a solar radiation model. In this section, the amount of solar radiation incident upon Earth is estimated using equations and relationships between the sun and the Earth. The second part is the optical model. This part has the ability to determine the optical efficiency of PTSC throughout the daytime. The last part is the thermal model. The aim of this section is to estimate the amount of energy collected by …

Understanding The Global Energy Crisis, Eugene D. Coyle, Richard A. Simmons

Purdue University Press Books

We are facing a global energy crisis caused by world population growth, an escalating increase in demand, and continued dependence on fossil-based fuels for generation. It is widely accepted that increases in greenhouse gas concentration levels, if not reversed, will result in major changes to world climate with consequential effects on our society and economy. This is just the kind of intractable problem that Purdue University’s Global Policy Research Institute seeks to address in the Purdue Studies in Public Policy series by promoting the engagement between policy makers and experts in fields such as engineering and technology.

Hydrogen Fueling Stations Infrastructure, Florida Solar Energy Center, Nan Qin

FSEC Energy Research Center®

Fuel Cell Electric Vehicles (FCEVs) can provide customers with the benefits of low to zero greenhouse gas emissions, high performance, and comfort without compromising range and refill time. With three major automakers (Honda, Hyundai, and Toyota) planning to introduce consumer FCEVs by the end of 2015, FCEVs will play an increasingly important role in the electric vehicle arena. Building hydrogen fueling infrastructure has been identified as a major obstacle in FCEV commercialization. This report is part of an ongoing effort within an Electric Vehicle Transportation Center (EVTC) project: "Fuel Cell Vehicle Technologies, Infrastructure and Requirements." This report is based on …

Energy And Peak Power Reduction From Air Misting Products Applied To Commercial Condensing Units In Hot And Humid Climates, Florida Solar Energy Center, Charles Withers, Jr.

FSEC Energy Research Center®

A proprietary research project was conducted to evaluate the potential annual and peak energy reduction resulting from the addition of a water misting system applied to supermarket condenser coils in the Florida Power and Light service territory. Tests were performed to evaluate the performance of a mist system under various outdoor conditions over an eight-month period in a hot and humid climate zone. The project measured an average of 2.8% percentage energy savings and average 3.2% utility peak demand reduction. The report discusses why hot and humid climates can expect much lower savings compared to hot and arid climates. One …

Water Transport Through Porous Media And In Flow Channels Of Proton Exchange Membrane Fuel Cell, Mehdi Mortazavi

Dissertations, Master's Theses and Master's Reports - Open

Proton exchange membrane (PEM) fuel cell has been known as a promising power source for different applications such as automotive, residential and stationary. During the operation of a PEM fuel cell, hydrogen is oxidized in anode and oxygen is reduced in the cathode to produce the intended power. Water and heat are inevitable byproducts of these reactions. The water produced in the cathode should be properly removed from inside the cell. Otherwise, it may block the path of reactants passing through the gas channels and/or gas diffusion layer (GDL). This deteriorates the performance of the cell and eventually can cease …

Computational And Experimental Study On Vertical Axis Wind Turbine In Search For An Efficient Design, Mohammad M. Bashar

College of Graduate Studies: Theses & Dissertations

Wind alone can fulfill most of the energy requirement of the world by its efficient conversion in to energy. Though Horizontal Axis Wind Turbine (HAWT) is more popular but needs high wind speed to generate energy. On the other hand Vertical Axis Wind Turbine (VAWT) needs low wind speed and can be installed anywhere which are some of the reasons for this research. The main objective of this research is to improve the design and performance of VAWT to make it more attractive, efficient, durable and sustainable. For a VAWT the blades perform the main role to extract energy from …
