dc.description.abstract Magnetohydrodynamics ows have gained signi cant attention due to their importance in engineering applications. In this study, we numerically analysed the Dufour and Soret e ects on an unsteady MHD mixed convection ow past an in nite vertical plate with viscous dissipation. The governing non-linear partial di erential equations (PDEs) are transformed into a system of ordinary di erential equations (ODEs) by the suitable similarity transformations. The resulting equations consist of the momentum, energy and mass di usion equations. These resulting equations are solved using the Spectral Local Linearization Method (SLLM). Results obtained by the SLLM are in good agreement with the bvp4c technique. The e ects of di erent physical parameters entering into the problem are displayed graphically. The values of the Skin-friction (f0(0)), Nusselt number (􀀀 0(0)) and Sherwood number (􀀀 0(0)) are shown in tabular form for di erent values of the parameters. From the results, it is noted that the Soret number (Sr) and the Dufour number (Du) have negligible e ects on temperature pro le, whereas the decrease in the Soret number (Sr) leads to a decrease in both velocity and concentration of the uid, and the increase in Dufour number (Du) reduces the velocity and also has negligilbe e ect on the concentration pro le. en_US
