Abstract
This study presents similarity solutions for steady laminar mixed convection boundary layer flow over a permeable horizontal surface of a wedge in a viscous and incompressible fluid. The similarity solutions of the governing boundary layer equations are obtained for some values of the suctions/injection parameter the constan exponent m of the wall temperature as well as the mixed convection parameter . The resulting system of nonlinear ordinary differential equations is solved numerically for both assisting and opposing flow regimes using an implicit finite-difference scheme. Numerical results for the skin friction coefficient, the local Nusselt number, and the velocity and temperature profiles are obtained for various values of parameters considered. Both assisting and opposing flows are considered. For the assisting flow the solution is unique, and both the skin friction coefficient and the local Nusselt number increase with , while for the opposing flow dual solutions are found to exist.
