Book Description
Convective heat transfer characteristics of a liquid cooled rectangular channel, containing offset plate fins were investigated experimentally. The selected geometry was a 10x model of the fluid circulation passages in the commercially available SEM-E type electronic cooling modules. The test surface containing fins was made of aluminum and was heated at its base by a thermofoil heater. The Reynolds numbers were varied between 100-800, with water as the cooling fluid. Surface temperature measurements on the heated surface were used to determine the Colburn j factor. The effects of natural convection were also investigated.

Book Description
The heat transfer characteristics and flow visualization of a 10X scale version of internal offset-fin plate array within the liquid flow-through module for electronics cooling were investigated experimentally using water as a cooling fluid. By varying power input settings and coolant flow rates, the heat transfer effect, from the plate array to the coolant water was investigated. Additionally thermochronic liquid crystals were spray-painted onto the plate to determine the temperature distribution within the heat transfer surface, as compared to the readings from the attached thermocouples. Finally a flow visualization using the dye-injection technique was to study the flow patterns of the coolant through the fin array.

Book Description
In this study, the offset strip fin array in a liquid flow liquid flow through module was examined. The study used a model of the heat exchanger which is ten times larger than the actual model used in electronics cooling. Water and Brayco Micronic 889 Polyalphasolefin were used as the working fluids in order to determine the Reynolds number and Prandtl number effects on the Colburn j factor. Also, flow visualization were experiments were performed to determine the flow characteristics of the offset strip fins for laminar flow.

Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book Description
Over the past few decades there has been a prolific increase in research and development in area of heat transfer, heat exchangers and their associated technologies. This book is a collection of current research in the above mentioned areas and discusses experimental, theoretical and calculation approaches and industrial utilizations with modern ideas and methods to study heat transfer for single and multiphase systems. The topics considered include various basic concepts of heat transfer, the fundamental modes of heat transfer (namely conduction, convection and radiation), thermophysical properties, condensation, boiling, freezing, innovative experiments, measurement analysis, theoretical models and simulations, with many real-world problems and important modern applications. The book is divided in four sections : "Heat Transfer in Micro Systems", "Boiling, Freezing and Condensation Heat Transfer", "Heat Transfer and its Assessment", "Heat Transfer Calculations", and each section discusses a wide variety of techniques, methods and applications in accordance with the subjects. The combination of theoretical and experimental investigations with many important practical applications of current interest will make this book of interest to researchers, scientists, engineers and graduate students, who make use of experimental and theoretical investigations, assessment and enhancement techniques in this multidisciplinary field as well as to researchers in mathematical modelling, computer simulations and information sciences, who make use of experimental and theoretical investigations as a means of critical assessment of models and results derived from advanced numerical simulations and improvement of the developed models and numerical methods.
