RÉSUMÉ

In this study, the mixed convection of water at 4°C along a wedge in a porous medium is investigated numerically using an implicit finite difference method. The Robin boundary condition is applied at the wedge surface. In order to explore the effects of mixed convection, both forced and free convection dominated regimes are considered separately. Non similarity solutions are obtained for the variable heat transfer coefficient. Local dimensionless skin friction and Nusselt number are presented in tabular and graphical forms for the selected values of wedge and convective parameters. The wedge angle geometry parameter m range from 0 to 1 in both regimes, whereas different values of mixed convection parameter ε and convective parameter hc are considered for investigating the behavior of skin friction and heat transfer rates.
