Life Cycle Performance Evaluation of an Air-Based Solar Thermal System
(University of Wisconsin-Madison, 2000)Performance at the McKay center after 22 years of operation was characterized through experimental measurements of component parameters. Effects of the component parameters on systems level performance was evaluated ... -
Local Heating During Electron Beam Patterning of Lithography Masks
(University of Wisconsin-Madison, 1998)The semiconductor industry is constantly seeking to improve the performance of integrated circuits by drastically increasing the density and reducing the pattern feature size. Accurate patterning of advanced lithography ... -
Local Liquid Velocity Measurements in Horizontal, Annular Two-Phase Flow
(University of Wisconsin-Madison, 2004)Two-phase annular flow is commonly used in both commercial and industrial heat transfer; however, we do not yet possess a thorough understanding of the nature of the fluid. Most analytical annular two-phase models are ... -
Localized Resist Heating Due to Electron-Beam Patterning During Photomask Fabrication
(University of Wisconsin-Madison, 2001)As the semiconductor industry continues to shrink the size microelectronic components, sources of critical dimension error that were unimportant in the past have surfaced, and must be resolved. Among these errors is ... -
Low Firing Temperature Absorption Chiller System
(University of Wisconsin-Madison, 2000)Two types of the absorption chillers, the single and half effect cycles, can operate using low temperature hot water. The advantage of the single effect over the half effect cycle is the higher COP but the single ... -
Model and Design of an Air-Cooled Thermal Management System for an Integrated Motor/Controller
(University of Wisconsin-Madison, 2005)The use of a remote power supply for conventional induction-type electric motors requires that very high frequency, high power pulse-width modulated signals be transmitted through cables over a significant distance. ... -
Model and Test of an Actively Controlled Cryogenic Micro Valve
(University of Wisconsin-Madison, 2006)Future NASA missions require cooling of large optical structures, cryogen storage systems, and instrument chambers and therefore cooling must be applied in a controlled and efficient fashion over a large spatial extent. ... -
A Model-Based Fault Detection and Diagnosis Methodology for HVAC Subsystems
(University of Wisconsin-Madison, 1999)The existence of faults in Heating, Ventilating, Air-Conditioning and Refrigerating (HVAC&R) systems plays a significant role in the degradation of comfort levels for building occupants on one scale, and the degradation ... -
The Modeling of a Natural Convection Heat Exchanger in a Solar Domestic Hot Water System
(University of Wisconsin-Madison, 1994)The use of simulations can greatly aid in optimizing the design of natural convection heat exchangers (NCHEs) in solar domestic hot water (SDHW) systems. Fraser et al. (1992) presented a NCHE model that is used in the ...
