摘要：

In this study, the mixed convection of water at 4 degrees C along a vertical plate with prescribed surface heat flux in a porous medium is investigated numerically using the implicit finite difference method. Nonsimilar solutions are obtained for both forced convection- and free convection-dominated regimes. The velocity and temperature profiles are shown to explain the flow as well as temperature variation as a function of controlling parameters. Skin friction and Nusselt number are obtained and compared with the available numerical results for various values of different parameters. Several values of the heat flux variation parameter lambda and mixed convection parameter epsilon, are considered for the purpose of comparison of skin friction and heat transfer results.
