摘要

Magnetohydrodynamics flows have gained significant attention due to their importance in engineering applications. In this study, we numerically analyse the Dufour and Soret effects on an unsteady MHD mixed convection flow past an infinite vertical plate with viscous dissipation. The governing non-linear partial differential equations (PDEs) are transformed into a system of first order differential equations (ODEs) by the suitable similarity transformations. The resulting equations consist of the momentum, energy and mass diffusion equations. These resulting equations are solved numerically using the spectral local linearization method (SLLM). The results obtained by SLLM are in good agreement with the bvp4c technique. The effects of different physical parameters entering into the problem are displayed graphically. The values of the skin-friction (f'(0)), Nusselt number (-θ'(0)) and Sherwood number (-Φ'(0)) for different values of parameters are shown in tabular form.
