Abstract

An investigation is carried out to study MHD boundary layer flow, heat and mass transfer of an incompressible viscous fluid past a continuously moving nonlinear stretching porous sheet in porous medium with temperature dependent fluid properties subject to heat source, viscous dissipation, chemical reaction and suction. The fluid viscosity and the thermal conductivity are assumed to vary as an inverse function and linear function of temperature respectively. The governing nonlinear partial differential equations are converted into a system of coupled nonlinear ordinary differential equations by using similarity transformations and solved numerically by the Matlab’s built in solver bvp4c. The numerical results are presented graphically for velocity, temperature and concentration distributions. The skin friction, wall temperature and wall concentration gradients are tabulated for emerging parameters. It is arrived at a good agreement on comparing the present numerical results with previously published results. It is found that skin friction rises but wall temperature and wall concentration gradients fall with growing viscosity, magnetic field, stretching parameter and Darcy parameter respectively. The thermal conductivity parameter diminishes wall temperature gradient while the Schmidt number and chemical reaction parameter enhance wall concentration gradient.
