MHD Flow and Heat Transfer in the Flow of a Power Law Fluid Over a Non-ISO Thermal Stretching Sheet

Abstract

This article presents a numerical solution for the MHD flow of an electrically conducting non-Newtonian power law fluid over a semi-infinite non-isothermal stretching sheet with internal heat generation/ absorption. The flow is caused by linear stretching of a sheet from an impermeable wall. Thermal conductivity is assumed to vary linearly with temperature. The intricate coupled non-linear boundary value problem has been solved by a combination of Keller box method and shooting technique. An important observation of our study is that the velocity boundary layer thickness and thermal boundary layer thickness decreases with the increase of power law index in the presence / absence of variable thermal conductivity.
