Analysis of Soret and Dufour effect on MHD fluid flow over a slanted stretching sheet with chemical reaction, heat source and radiation (Q6599222)

A free-convection boundary-layer flow MHD flow subjected to Soret and Dufour effect over a slanted porous lamina is analyzed. The problem is formulated under Boussinesq approximation with continuity, momentum, energy and mass conservation equations. A similarity transformation is introduced to convert the continuity and momentum equations into highly coupled nonlinear ordinary differential equations of fourth order along with the coupled nonlinear ordinary differential equations of order two for energy and mass conservations. These equations are solved by fourth-order Runge-Kutta method using the commercial MATLAB software. The initial guesses are made by using shooting method. Several results are depicted graphically, and it is observed that fluid velocity rises with the increase in the heat transfer coefficient, Biot number and concentration buoyancy number. Fluid velocity reduces due to increase in Soret and Duffour effects in both suction and injection cases.\N\NFor the entire collection see [Zbl 1522.00198].
