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. === NRF
