Magnetohydrodynamic viscous–Ohmic dissipation performance on unsteady convective heat transfer over a stretching surface in existence of internal heat generation/absorption

Abstract

This article is devoted to the study of convective flow of an electrically conducting fluid over an unsteady stretching permeable sheet with transverse magnetic field and internal heat source–sink with viscous–Ohmic heating effects. The dimensionless governing ordinary nonlinear differential equations have been solved numerically for opposing and assisting flows. The effects of unsteadiness parameter, buoyancy parameter, the mass suction-injection parameters, Eckert number, and internal heat source–sink parameter on the boundary layer flow and heat transfer distribution are thoroughly analyzed. Comparison of the present results with the earlier published results is performed for steady case and the results show excellent agreement.
