A computational study is conducted to examine the fully developed laminar flow and heat transfer characteristics in parallel plate channels with internal, longitudinal, corrugated fins. The fins are integrally attached to the upper an lower channel walls. The objective of the study is to determine the effects of varying the fin angle, the fin thickness, the ratio of thermal conductivity of the channel wall to that of the fluid, and the thermal boundary conditions on the channel heat transfer and pressure drop. The solutions of the momentum and energy equations are obtained by using a control volume based finite difference algorithm. The results of the study include the relative heat transfer and the relative pressure drop, defined as the finned channel heat transfer and pressure drop divided by the corresponding heat transfer and pressure drop for a parallel plate channel with no fin. The distributions of the local temperature and the local heat flux along the exposed channel wall and fin surfaces, and the detailed two dimensional velocity and temperature fields are also obtained. This information is applicable to the design of single-phase cold plates for cooling electronic equipment in the proposed space station and the design of heat exchangers in general. |
