Numerical and Experimental Study of Small Engine Carburetors
(University of Wisconsin-Madison, 2005)Due to price constraints, small engines rely on inexpensive and mechanically-simple de- vices for air-fuel mixture formation: carburetors. A typical carburetor consists of a complex set of internal passages designed ... -
Numerical and Experimental Study of the Influence of Frost Formation and Defrosting on the Performance of Industrial Evaporator Coils
(University of Wisconsin-Madison, 2006)The main objective of an evaporator in any refrigeration system is to extract thermal energy from a conditioned space by recirculating air through a refrigerated coil. However, when an air-cooled evaporator operates at ... -
A Numerical Model of an Active Magnetic Regenerator Refrigeration System
(University of Wisconsin-Madison, 2005)Active magnetic regenerator refrigeration (AMRR) systems are an environmentally attractive space cooling and refrigeration alternative that do not use a fluorocarbon working fluid. Two recent developments have made ... -
Numerical Modeling and Experimental Testing of a Mixed Gas Joule-Thomson Cryocooler
(University of Wisconsin-Madison, 2006)Mixed gas Joule-Thomson (MGJT) systems have been shown to provide order of magnitude improvements in efficiency relative to JT systems that use pure working fluids. This thesis presents theoretical and experimental ... -
The Optimal Control of Ice-Storage Air-Conditioning Systems
(University of Wisconsin-Madison, 1993) -
Optimal Design and Operation of Solid Oxide Fuel Cell Systems for Small-scale Stationary Applications
(University of Wisconsin-Madison, 2002)The advent of maturing fuel cell technologies presents an opportunity to achieve significant improvements in energy conversion efficiencies at many scales; thereby, simultaneously extending our finite resources and ... -
Optimization of Cryosurgical Probes for Cancer Treatment
(University of Wisconsin-Madison, 2004)We take for granted the abundance and variety of food that is available to us all year round. Grocery stores around the U.S and the world sell a wide variety of fruits and vegetables throughout the year no matter when ... -
Optimization of Direct-Contact-Spray-Coolers
(University of Wisconsin-Madison, 2002) -
Optimized Combination of a Cooling Pond and Cooling Tower System for Condenser Cooling at a Steam Cycle Power Plant
(University of Wisconsin-Madison, 1995)The performance of the condenser cooling cycle of a steam cycle power plant is examined for the Columbia Generating Station of the Wisconsin Power & Light Company located near Portage, Wisconsin. The Columbia station ... -
Optimum Selection of Direct-Coupled Photovoltaic Pumping System in Solar Domestic Hot Water Systems
(University of Wisconsin-Madison, 1997)The performance of photovoltaic powered pumps in direct and indirect solar domestic hot water (PV-SDHW) systems has been studied. The direct PV-SDHW system employs a photovoltaic array, a DC-motor, a centrifugal pump, ... -
Ozone in Direct Contact Spray Air Conditioning Systems
(University of Wisconsin-Madison, 2000) -
Parameter Estimation and Optimal Supervisory Control of Chilled Water Plants
(University of Wisconsin-Madison, 1998)The objective of the work is to develop methods for minimizing the energy costs of chilled water systems through optimal control. The general approach includes the following tasks: 1) proposing a system of parametric ... -
Parameter Estimation and the Use of Catalog Data with TRNSYS
(University of Wisconsin-Madison, 1997)Due to assumptions, idealizations, and detailed specifications often required by existing TRNSYS components, difficulties are encountered in modeling the performance of cataloged components within TRNSYS transient thermal ...
