• MHD CONVECTIVE FLOW OVER A VERTICAL SURFACE WITH RESPECT TO POROSITY AND MASS DIFFUSION

E. RAGHUNANDANA SAI SAI, CH. V. RAMANA MURTHY*

Abstract


The influence of critical parameters on the velocity of fluid medium in case of MHD convective flow over a vertical surface with respect to porosity and mass diffusion has been studied in this paper. It is observed that, as the magnetic intensity increases, the velocity of the fluid decreases and also, as Prandtl number increases, the velocity increases. Further, it is seen that as we move far away from the boundary, the velocity increases. In addition to the above, it is observed that, as Schmidt number increases, the velocity of the fluid decreases.  Also, as magnetic intensity increases, the fluid velocity decreases. It is noticed that, as the smith number increases, the velocity decreases. Though there is a significant change in the Schmidt number, not much of appreciable change in the velocity profile is noticed.
