Self-Optimizing Control Of Cooling Tower For Efficient Operation Of Chilled Water Systems, Xiao Li, Yaoyu Li, John E. Seem, Pengfei Li

International High Performance Buildings Conference

The chilled-water systems, mainly consisting of electric chillers and cooling towers, are crucial for the ventilating and air conditioning systems in commercial buildings. Energy efficient operation of such systems is thus important for the energy saving of commercial buildings. This paper presents an extremum seeking control (ESC) scheme for energy efficient operation of the chilled-water system, and presents a Modelica based dynamic simulation model for demonstrating the effectiveness of the proposed control strategy. The simulated plant consists of a water-cooled screw chiller and a mechanical-draft counter-flow wet cooling tower. The ESC scheme takes the total power consumption of the chiller …

Combined Heat And Moisture Transfer In Buildings Systems, Rashmin Damle, Oriol Lehmkuhl, Joaquim Rigola, Assensi Oliva

International High Performance Buildings Conference

Temperature and humidity are the two main parameters indicating the comfort level of the building occupants. Although the effect of temperature is taken into account in thermal simulation of buildings, the moisture transfer through the rooms and porous building walls is sometimes neglected. The level of humidity can give different sensations of thermal comfort. It is necessary to take into account both heat and moisture transport in and around buildings to predict the hygrothermal behavior of rooms and building walls so as to calculate the energy demands correctly. In this work some benchmark exercises are worked out to see the …

Characterization of 1 mm thick wicks composed of 100 lm sintered copper particles is performed in a test facility which replicates the capillary feeding conditions that occur in such devices. Boiling curves are obtained for a 5 mm x 5 mm heated input area, along with high-speed in-situ visualization of the evaporation/boiling processes. Understanding the vapor formation regimes is essential to predictive modeling of the observed characteristics. Schematic …

Comparison Of Equation-Based And Non-Equation-Based Approaches For Transient Modeling Of A Vapor Compression Cycle, Hongtao Qiao, Vikrant Aute, Reinhard Radermacher

International Refrigeration and Air Conditioning Conference

Transient modeling methods can also be classified into two categories based on equation specifications. The first category of methods are non-equation based methods, in which one has to describe the underlying physics with fundamental equations, formulate residual equations and provide an algorithm to solve the underlying nonlinear equations. The second category of methods are equation based methods, wherein the engineer only has to specify the underlying physics, that holds for each time step, in the form of equations and use an established modeling platform or a solver which will handle the formulation and solution of underlying nonlinear differential algebraic equations. …

1d Heat Exchanger Simulation To Capture The Cycling Transients Of Domestic Refrigeration Appliances Working With R600a, Erwin Berger, Martin Heimel, Raimund Almbauer, Wolfgang Lang

International Refrigeration and Air Conditioning Conference

To further increase the energy efficiency of domestic refrigeration systems, it is not sufficient anymore to optimize the single cycle components on their own. On the contrary, due to the strong system interactions, an integral consideration of the whole cooling cycle is necessary to capture the system dynamics in detail and to understand them. Just by understanding the occurring physical effects, loss mechanisms can be identified and efficient optimizing measures could be taken. In this work a transient model for the simulation of the evaporator and the condenser of domestic refrigeration appliances, based on the Finite Volume Method (FVM) is …

Carbon Nanotube Coatings For Enhanced Capillary-Fed Boiling From Porous Microstructures, J. A. Weibel, S. S. Kim, T. S. Fisher, S V. Garimella

CTRC Research Publications

Due to their high intrinsic thermal conductivity, carbon nanotubes (CNTs) have previously been incorporated into a variety of thermal management applications to improve cooling performance. Implementation of controlled CNT growth techniques and functionalization methods are applied herein to enhance boiling heat transfer from the porous capillary wicking surfaces widely used in high heat flux thermal management devices. A microwave plasma-enhanced chemical vapor deposition (MPCVD) synthesis process resulted in growth of a permeable CNT coating, and physical vapor deposition of copper over these nanotubes yielded the requisite hydrophilic wicking surface. An array of test samples was fabricated and then evaluated using …

Second-Law Analysis Of Molten-Salt Thermal Energy Storage In Thermoclines, S. Flueckiger, S V. Garimella

The cyclic operation of a molten-salt thermocline tank is simulated to investigate the influence of internal granule diameter and external convection losses on tank performance. Practical constraints limiting thermocline tank height are taken into account. The authors two-temperature model, developed in earlier work (Solar Energy, 84, 974–985, 2010) for the analysis of heat transfer and fluid flow in the thermocline tank, is extended to monitor entropy generation and exergy transport. Storage performance is measured in terms of first- and second-law efficiency definitions, as well as a first-law efficiency used in conjunction with an outflow temperature criterion. Reducing the diameter of …

Thermomechanical Simulation Of The Solar One Thermocline Storage Tank, S. Flueckiger, Z. Yang, S V. Garimella

CTRC Research Publications

The growing interest in large-scale solar power production has led to a renewed exploration of thermal storage technologies. In a thermocline storage system, heat transfer fluid (HTF) from the collection field is simultaneously stored at both excited and dead thermal states inside a single tank by exploiting buoyancy forces. A granulated porous medium included in the tank provides additional thermal mass for storage and reduces the volume of HTF required. While the thermocline tank offers a low-cost storage option, thermal ratcheting of the tank wall (generated by reorientation of the granular material from continuous thermal cycling) poses a significant design …

Numerical Investigation Of An Evaporating Meniscus In A Channel, H. K. Dhavaleswarapu, J. Y. Murthy, S V. Garimella

CTRC Research Publications

A detailed numerical model is developed that describes heat and mass transfer from a meniscus to open air. The model accounts for the effects of evaporation at the interface, vapor transport through air, ther- mocapillary convection, and natural convection in air. Evaporation at the interface is modeled using kinetic theory, while vapor transport in air is computed by solving the complete species transport equa- tion. Since the vapor pressure at the liquid–gas interface depends on both evaporation and the vapor transport in air, the equations are solved in an iterative manner. Evaporation is strongest at the triple line due to …

Wicking And Thermal Characteristics Of Micropillared Structures For Use In Passive Heat Spreaders, R. Ranjan, A. Patel, S V. Garimella, J. Murthy

CTRC Research Publications

The thermal and hydrodynamic performance of passive two-phase cooling devices such as heat pipes and vapor chambers is limited by the capabilities of the capillary wick structures employed. The desired char- acteristics of wick microstructures are high permeability, high wicking capability and large extended meniscus area that sustains thin-film evaporation. Choices of scale and porosity of wick structures lead to trade-offs between the desired characteristics. In the present work, models are developed to predict the capillary pressure, permeability and thin-film evaporation rates of various micropillared geometries. Novel wicking geometries such as conical and pyramidal pillars on a surface are proposed …

Direct Simulation Of Thermal Transport Through Sintered Wick Microstructures, K. K. Bodla, J. Y. Murthy, S V. Garimella

CTRC Research Publications

Porous sintered microstructures are critical to the functioning of passive heat transport devices such as heat pipes. The topology and microstructure of the porous wick play a crucial role in determining the thermal performance of such devices. Three sintered copper wick samples employed in commercial heat pipes are characterized in this work in terms of their thermal transport properties––porosity, effective thermal conductivity, permeability, and interfacial heat transfer coefficient. The commercially available samples of nearly identical porosities (61% open volume) are CT scanned at 5.5 lm resolution, and the resulting image stack is reconstructed to produce high-quality finite volume meshes representing …

Thermal-Hydraulic Performance Of Metal Foam Heat Exchangers, Kashif Nawaz, Jessica Bock, Anthony M. Jacobi

International Refrigeration and Air Conditioning Conference

Due to their large surface-area-to-volume ratio and tortuous structure, metal foams hold promise for heat transfer applications. Both of these factors increase the heat transfer by enhancing the mixing and surface area. The main disadvantage associated with their thermal-hydraulic performance is relatively higher pressure drop, resulting in larger pumping power requirements if they are used in a heat exchanger. In this paper, open-cell aluminum metal foam is considered as a highly compact replacement for conventional fins in brazed aluminum heat exchangers. SEM techniques are used to characterize the foam characteristics such as pore and ligament diameter. Experiments are conducted by …

Dual-Mode Wicking Structures For Enhanced Evaporative Heat Transfer, Shankar Krishnan, Ward E. Tegrotenhuis

International Refrigeration and Air Conditioning Conference

This paper reports on conceptual design and thermo-fluid characteristics of two-phase flow devices enabled by dualmode wicks. In dual-mode wicking structures, liquid and vapor flow paths are integrated on the same plane and segregated flow of the two-phases is achieved by having networks of pores of multiple length-scales. When a mixture of a gas and a liquid flow through this media and the wick material wets the liquid, then the liquid will preferentially segregate to and flow through the mode with the smaller effective pore size. The gas will flow through the paths with the larger effective pore size. These …

Security Implications Of The Cisco Nexus 1000v, Benjamin D. Peterson

Purdue Polytechnic Masters Theses

Virtualization is a technology that has become increasingly popular with those wishing to reduce the energy consumption of their datacenters. This is especially true since virtualization technology allows multiple physical servers to be consolidated onto a single physical server in the form of virtual machines. Virtual networking devices have been created to allow these virtual machines to communicate amongst each other and with outside networks. Initially these virtual networking devices were crude; however, partnerships such as the one between Cisco and VMware have led to products such as the Nexus 1000V that have improved this network functionality. Despite the creation …

An Optimization Approach To Indoor Location Problem Based On Received Signal Strength, Lei Zheng

Browse all Theses and Dissertations

This research was motivated by the desire of a Fortune 100 retail company to track its customers' behaviors through the implementation of a low-cost indoor location system using received signal devices. Indoor location through received signal strength (RSS) is of low costs, yet it suffers from poor accuracy due to lack of direct line-of-sight, multi-path ratio propagation, and various interferences. To improve its location estimation accuracy, therefore, we propose a mathematical programming based propagation approach for RSS based location systems. The core of our approach is an optimization model that minimizes the sum of squared errors of signal strength. In …

When Laws And Representation Are Not Enough: Enduring Impunity And Post-Conflict Sexual Violence In Liberia And Sierra Leone, Ashley D. Kitchen

Browse all Theses and Dissertations

Throughout the course of history, literature and examination on the impact of civil war has focused little on women, especially in the cases of wartime rape. While the factors which sustain wartime rape are examined with frequency, using gender as an analytical lens, the analysis regarding post-conflict sexual violence and rape is studied far less, leading to the question: what factors are correlated with the continuance of widespread acts of rape even after the cessation of official conflict? Liberia and Sierra Leone suffered high levels of both wartime rape and also post-conflict sexual violence. This comparative case study, using process …

Knowledge-Enabled Engineering Design: Toward An Integrated Model, Michael Fosmire, David Radcliffe

Libraries Faculty and Staff Scholarship and Research

Librarians and engineering faculty have long understood that design is one of the defining processes of the engineering profession. In an increasingly knowledge-driven society, students need to efficiently locate, assess and integrate relevant information into their design process so that they can develop innovation solutions to emerging complex, global grand challenges. Increasingly, engineering curricula are incorporating design as early as the first year, but a question remains as to how effectively information literacy is being integrated into these early experiences of design. For example, the Engineering Change study found there has been very little improvement to lifelong learning skills in …
