Abstract :The influence of permeability of the porous plate on double diffusive MHD mixed convective flow past an inclined porous plate in the boundary layer region has been investigated in this paper. The system of non-linear partial differential equations and their boundary conditions have been developed, and transformed into a set of non-linear ordinary differential equations with the help of similarity transformations. These transformed equations are solved numerically for different values of relevant parameters using Runga-Kutta method with Nachtsheim-Swigert shooting iteration technique. Numerical results are obtained for the velocity, temperature and concentration distributions as well as local skinfriction, local Nusselt number and local Sherwood number, and presented graphically to analyze the effects of permeability parameters of the porous plate and the porous medium, and Eckert number. For some specific values of relevant governing parameters, the numerical result is compared with those available in the literature for validity of numerical results and a comparatively good agreement is reached
