Brown, Jay A. Koc,̕ Paul Frantisek Glicksman, Leon R. The methodology utilized for the design of a forced-cooled pipe-type underground transmission system is presented. The material is divided into three major parts: (1) The Forced-cooled Pipe-Type Underground Transmission System Design Manual-Part I, (2) The Design Manual-Part II, and (3) the Forced-Cooled Pipe-Type Underground Transmission System Computer Program Design Manual. The Design Manual Part I provides the thermal and hydraulic design analyses required for the design of a forced-cooled cable system of specified geometry. The thermal design establishes the relationship between the cable amperage, oil flow, and the conductorto- oil temperature difference and provides a coolant loop energy balance which includes an analysis of the pipe-to-soil heat transfer. Combination of both permits the maximization of the cable amperage while maintaining the cable temperature below the maximum allowable value. The hydraulic design establishes the pressure-flow characteristics for pipe-type cable systems and a systematic analysis is provided which allows for calculation of the pressure drop in the cable line and rturn line of the flow circuit as well as the circuit absolute pressure profile. The pressure drop governs the selection of circulation pumps, pipe strength characteristics, and strongly influences coolant loop length. The Design Manual-Part II presents a description of the experimental and analytical research performed at M.I.T.'s Heat Transfer Laboratory which provides the relationships used in the design analysis of Design Manual-Part I. The Computer program design manual provides a detailed description of the forced-cooled system computer program and the necessary program documentation. The computer program is basically a straightforward computerization of the design procedure of Design Manual- Part I. Six different computer design options are provided which permit complete flexibility for the design and optimization of the forced-cooled system. Four of the design options allow for the selection of alternative independent and dependent design variables and two design options provide for the system optimization based on specified optimization criteria. 2011-01-14T22:45:38Z 2011-01-14T22:45:38Z 1978 http://hdl.handle.net/1721.1/60605 10849122 Energy Laboratory report (Massachusetts Institute of Technology.
