Description
Summary:The increasing demand for high-performance electronic devices and surge in power density accentuates the need for heat transfer enhancement. In this study, a thermal viscous dissipative Couette flow and Couette-Poiseuille flow in a channel filled with fluid saturated porous medium is looked into. Two cases of thermal boundary condition are considered: constant heat flux is applied on the moving wall while the fixed plate is insulated, and both plates are subjected to constant heat flux. The study would explore the fluid flow and heat transfer phenomenon for Couette flow and Couette-Poiseuille flow in a channel as well as to establish the relationship between the heat convection coefficient and viscous dissipation. A fully developed flow and local thermal equilibrium are assumed in the analysis. An analytical Nusselt number expression is developed for Couette flow and Couette-Poiseuille flow in terms of Brinkman number as a result of this study, thus providing essential information to gauge the thermal performance of a channel. The results obtained without viscous dissipation are in close agreement with published results for Couette flow and CouettePoiseuille flow.
