Numerical simulation of MHD boundary layer flow and heat transfer over a nonlinear stretching sheet in the porous medium with viscous dissipation using hybrid approach

Abstract

In the present study, MHD boundary layer flow with heat and mass transfer of a nanofluid with viscous dissipation over a non-linear stretching sheet embedded in a porous medium is studied. The governing non-linear partial differential equations are converted into coupled non-linear ordinary differential equations which are solved by hybrid technique consisting of finite element method with symbolic computation. The effect of Viscous dissipation, magnetic influence parameter, permeability parameter, Brownian motion, Eckert number, Thermophoresis parameter, Prandtl number parameter, Dufour Lewis number and nanofluid Lewis number are studied for velocity $(f'(\eta))$, temperature $(\theta(\eta))$, concentration of salt ($S(\eta)$) and concentration of nanoparticles $(\gamma(\eta))$ and results are shown graphically. Applications of such type of problems are found in the electromagnetic control of complex magnetic nanofluid materials relevant to energy and biomedical systems.
