Abstract

An investigation employing numerical methods has been conducted to present the Soret effects on magnetohydrodynamic (MHD) Unsteady Stagnation Point nano fluid Flow over an exponentially porous stretching sheet in existence of joule heating, thermal radiation, viscous dissipation, time dependent heat source or sink, chemical reaction and suction or blowing. With the use of MATLAB's bvp4c solver, the leading time dependent PDEs may be reduced to a family of non-linear ODEs and numerically solved. The influence of relevant flow parameters on temperature, concentration and velocity distribution are demonstrated graphically. For different controlling parameters, Sherwood and Nusselt number along with the skin-friction coefficient are also tabulated. There is a fairly close agreement between the current outcome and the previously announced result.
