This book was released on 1988 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural convection liquid cooling of simulated electronic components in a vertical channel was investigated. The test surface contained a single column of eight rectangular, protruding heated elements, each simulating a 20 pin dual-in-line package. Temperature measurements and flow visualization were performed for a number of power dissipation levels and channel widths. Collectively, this information was used in interpreting the flow and transport characteristics. A correlation to predict the heat transfer rates was developed based on the component surface temperatures. Optimum channel widths were determined from these surface temperature measurements for the range of power levels investigated. Temperature distributions in the fluid were measured using a traversing thermocouple probe. Keywords include: Natural convection; Immersion cooling; Protruding heat sources; Vertical channel; and Flow visualization, Theses. (RH).

This book was released on 1988 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural convection from a single column of eight in-line, rectangular, flush heat sources was examined. A vertical channel was formed by placing a movable shroud parallel to the test surface. The experimental program consisted of temperature measurements and flow visualizations. For a range of component power levels and channel spacings, surface temperatures of each heat source were measured at five locations using embedded thermocouples. The resulting steady state data was compared with corresponding measurements for an identical geometric arrangement of protruding heat sources. The flow visualization was carried out using a laser generated plane of light. Keywords: Convective flow, Thermal transport, Flow visualization, Theses. (JHD).

This book was released on 1989 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural convection liquid cooling of simulated electronic components in a vertical channel was investigated. The test surface consisted of three columns of fifteen flush mounted foil heaters. The channel was formed by placing a smooth movable shrouding wall parallel to the test surface. The experimental procedure called for temperature measurements and flow visualization at various power levels and channel spacings. Surface temperatures of each heat source were measured using a centrally located embedded thermocouple. Temperature measurement within the flow was conducted using a thermocouple probe. Flow visualization was conducted with the use of a laser generated plane of light. A visual temperature profile of the board was developed through the use of liquid crystals. From the data obtained, experimental correlations relating the local heat transfer properties with shroud wall spacing and strip heater power levels were developed. Keywords: Convective flow; Thermal transport; Flow visualization; Theses. (jhd).

This book was released on 1988 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation of natural convection immersion cooling of two configurations of discrete heat sources in an enclosure filled with Fluorinert FC-75 has been conducted. A three by three array of rectangular protrusions was employed. In the first study, using the same equipment set-up of Benedict, the influence of changing the enclosure bottom surface boundary condition of flow patterns and heat transfer characteristics was examined. Both insulated and uniform temperature boundary conditions were considered. In the second set of experiments, a new chamber with the protrusions oriented vertically was assembled and effects of component orientation on the heat transfer characteristics were examined. In addition, timewise variations of temperature in several locations were measured an interpreted a different power levels. Theses.

This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination 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 con cerned if the printing and distribution of the volumes were handled by an interna tional 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 Cor poration 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 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Design with Constructal Theory written by Adrian Bejan and published by John Wiley & Sons. This book was released on 2008-09-09 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Design course on the universal principle of configurations in nature and engineering-the constructal law Design with Constructal Theory offers a revolutionary new approach based on physics for understanding and predicting the designs that arise in nature and engineering, from the tree and the forest to the cooling of electronics, urban design, decontamination, and vascular smart materials. This book shows how you can use the method of constructal theory to design human-made systems in order to reduce trial and error and increase the system performance. First developed in the late 1990s, constructal theory holds that flow architecture arises from the natural evolutionary tendency to generate greater flow access in time and in flow configurations that are free to morph. It unites flow systems with solid mechanical structures, which are viewed as systems for the flow of stresses. Constructal theory unites nature with engineering, and helps us generate novel designs across the board, from high-density packages to vascular materials with new functionalities (self-healing, self-cooling), and from tree-shaped heat exchangers to svelte fluid-flow and solid structures. Design with Constructal Theory starts with basic principles and then shows how these principles are applied to understanding and designing increasingly complex systems. Problems and exercises at the end of each chapter give you an opportunity to use constructal theory to solve actual design problems. This book is based on a design course developed by the two authors for upper-level undergraduates and graduate students at Duke University and other universities all over the world. With the authors' expert guidance, students and professionals in mechanical, civil, environmental, chemical, aerospace, and biomedical engineering will understand natural systems, and then practice design as science, by relying on constructal strategies to pursue and discover novel and effective designs.
