MHD mixed convection flow over a permeable non-isothermal wedge

Numerical solutions are obtained for the hydro-magnetic mixed convection boundary layer flow of an electrically conducting fluid over a non-isothermal wedge in the presence of variable thermal conductivity. The effects due to viscous dissipation, internal heat generation/absorption, thermal radiation, Joule heating and stress work are included. The governing partial differential equations of the problem, subjected to the appropriate boundary conditions are solved numerically by an efficient finite difference scheme. Numerical calculations are carried out for several sets of values of the dimensionless parameters and a careful study of the results obtained reveal that the flow field is influenced appreciably by the applied magnetic field in addition to the other parameters. Numerical results for the velocity and temperature fields, the local skin-friction coefficient and the local Nusselt number are presented graphically and discussed. To validate the numerical method, comparisons are made with the available results in the literature as special cases and the results are found to be in good agreement. The results obtained reveal many interesting behaviors that warrant further study of the flow and heat transfer characteristics over the permeable wedge.
