Influence of viscous dissipation and variable suction on steady mhd mixed convection flow past a vertical porous flat plate with dufour and soret effects

This work is focused on the influence of Viscous dissipation and variable suction on free-combined flow past a semi-infinite vertical flat plate with Dufour and soret effects under the influence of transversely applied magnetic field, have been studied numerically. The resulting governing equations are transformed into non linear ordinary differential equations using similarity transformation. The set of non linear ordinary differential equations are first linearized by using Quasi-linearization technique and then solved numerically by using implicit finite difference scheme. Then the system of algebraic equations is solved by using Gauss-Seidal iterative method. Numerical results of hydrogen-air mixture fluid for the velocity, temperature and concentration are shown graphically for various values of the parameter entering into the problem.
