Main Article Content
The present work provides an analysis of the hydro-magnetic Nanofluid boundary layer flow over a rotating disk in a porous medium with a constant velocity in the presence of hall current and thermal radiation. The governing partial differential equations system that describes the problem is converted to a system of ordinary differential equations by the similarity transformation method, which solved analytically using Optimal Homotopy Asymptotic Method (OHAM). The velocity profiles and temperature profiles of the boundary layer are plotted and investigated in details. Moreover, the surface skin friction, rate of heat transfer are deduced and explained in details.
