摘要: Heat Pipe is a thermodynamic device which transports heat from one location to another with very small temperature drop. Entropy generation can be considered as significant parameter on pipe performance. Major reasons for entropy in system are difference between cold and hot reservoirs, frictional losses the working fluid flows vapor temperature/pressure drop along pipe. The objective of present work estimate flat A computational model developed analysis transient operation involves solution two dimensional continuity, momentum energy equations core transport porous medium wick. depends both velocity variations liquid. Alternating Direction Implicit (ADI) scheme used convert partial differential into finite equa...
