MHD effects on Darcy-Forchheimer mixed convection in a fluid saturated porous media with chemical reaction and viscous dissipation

摘要

The effects of MHD on the flow of mixed convection and mass transfer of a steady laminar boundary layer about an isothermal vertical flat plate embedded in a Non-Darcian porous medium in the presence of chemical reaction and viscous dissipation is analyzed. The governing partial differential equations are converted into ordinary differential equations by similarity transformations. The coupled nonlinear ordinary differential equations are linearized by Quasi-linearization technique. The linear ordinary differential equations are solved by using implicit finite difference scheme with the help of C-programming. Numerical calculations are carried out for different values of dimensionless parameter and an analysis of the results obtained shows that the flow field is influenced appreciably by the magnetic effect, chemical reaction, mixed convection parameter, inertia parameter, Schmidt number, buoyancy ratio parameter, Eckert number and Prandtl number. On the other hand, the local Nusselt number and the local Sherwood number also presented graphically.
