This book was released on 1964 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical study of a flat condenser-radiator with a double fin-tube geometry (closed sandwich) with variable tube side-wall thickness was performed for a Rankine space-power electric-generating system. The analysis of the double fin radiator included consideration of tube and header pressure drops, meteoroid protection for the tubes and headers, along with a detailed presentation of the heat rejection analysis and total weight characteristics. The double fin-tube radiator is compared to a conventional central fin-tube configuration on a heat rejection to weight basis for a four-panel radiator configuration. Both fin and tube geometries are compared on the basis of the same power level, working fluid temperature, tube and header pressure drop, radiator material, and meteoroid protection criteria. A beryllium radiator for a 1-megawatt system and a columbium alloy radiator for a 5OO-kilowatt system, both at a radiating temperature of 1700 R, were chosen for the weight and geometry comparison. The conclusion reached indicates a substantial weight savings can be realized with the double fin-tube arrangement if the tube side-wall thickness can be reduced as a result of a possible meteoroid bumper effect of the enclosing fins. Weight reductions compared to the central fin-tube geometry of up to 32 to 39 percent were shown to be possible for the maximum reduction in side- wall thickness in the two examples considered. This result further substantiated the preliminary conclusions given in an earlier reference that compared the double and central fin-tube configurations neglecting the effects of headers, pressure drops, tube wall temperature drop, and powerplant thermodynamic cycle considerations.

Download or read book Analysis and Evaluation of a Vapor chamber Fin tube Radiator for High power Rankine Cycles written by Henry C. Haller and published by . This book was released on 1965 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical investigation of a flat, direct- condensing fin-tube radiator employing segmented vapor-chamber fins as a means of improving heat rejection was performed A for illustrative high-power, high-temperature Rankine_space power electric generating systems. A vapor- chamber fin is obtained by replacing the conventional single solid fin with a double wall fin that forms a hollow chamber between tubes. A working fluid in the chamber can then be boiled off the tube surface and condensed on the fin surface of the chamber to produce a fin of constant temperature. Condensate is then returned to the boiling surface by some means of capillary pumping. The analysis of the vapor-chamber fin-tube radiator considered pressure drop in the radiator tubes and headers, meteoroid protection for the tubes headers, and vapor-chamber fins, and temperature drop in the tube armor in the develop ment of the descriptive equations. The heat transfer, weight, and geometric characteristics of the vapor-chamber fin-tube radiator were determined over a wide range of variables for two illustrative radiator design applications.

Available in PDF, EPUB and Kindle. Book excerpt: Solar Energy in Developing Countries is a documentation report with bibliography on solar energy research and development in developing countries such as those in Asia, Central and South America, Africa, and Middle East. Institutions in developed countries with solar activities of interest to developing countries are included. This volume consists of seven chapters and opens with an overview of the study followed by a discussion on solar activities of relevance to developing countries, focusing on the work of international or supranational organizations such as the United Nations, NATO, and the European Economic Community. The following chapters deal with the state of the art of solar energy applications as well as solar R&D work in developing countries, including solar distillation, solar cooking and drying, and solar refrigeration and air conditioning. Information and addresses on sources of literature, hardware and equipment are also provided, along with a detailed and comprehensive bibliography (mostly with abstracts). This book is intended for solar scientists and engineers, government officials, and others who are interested in solar R&D work in developing countries.
