碩士 === 國立暨南國際大學 === 土木工程學系 === 97 === Two-dimensional, steady, fully developed incompressible flow and heat transfer of a fluid-saturated porous medium in a vertical double-passage channel are investigated. The channel is divided into two passages by means of a thin, perfectly conductive baffle and the walls are uniformly heated by three types; say, symmetric, asymmetric and one side adiabatic. The porous effect is considered in momentum equation, whereas the viscous and Darcy dissipations are considered in energy equation. The governing equations have been numerically analyzed employing finite-difference method. The results show that the velocity and temperature profiles depend on the baffle position, the values of the ratio between Grashof and Reynolds number (0, 50, 100), Brinkman number (0.001, 0.01, 0.05, 0.1) , ratio of viscosity (0.5, 1, 2) and porous medium parameter (1, 10, 100).
