Abstract

The behavior of the steady convective heat transfer of an electrically conducting fluid flow over a porous wedge with uniform suction or injection was investigated. The wall of the wedge is embedded in a uniform porous medium in order to allow for possible fluid wall suction or injection. The governing boundary layer equations are written into a dimensionless form by similarity transformations. Because of the effect of suction/injection on the wall of the wedge with buoyancy force and variable wall temperature, the flow field is locally nonsimilar. The nonsimilar ordinary differential equations were obtained by means of a local nonsimilarity method. The resulting ordinary differential equations are solved by Runge-Kutta-Gill with a shooting method for finding a skin friction and a rate of heat transfer. The effects of suction/injection, nonuniform wall temperature and buoyancy force parameters on the dimensionless velocity and temperature profiles are shown graphically. Comparisons to previously published works are performed, and excellent agreement between the results is obtained. The conclusion is drawn that the flow field and temperature profiles are significantly influenced by these parameters.
