MHD flow properties due to a porous rotating disk in a mixed convective fluid flow with buoyancy and radiation

Abstract

The importance and differs applications of Magnetohydrodynamics, MHD and mixed convective flow through a porous medium has led to investigation of buoyancy force and thermal radiation on the flow. The modeled ordinary differential equations were transformed by means of similarity transformation into partial differential equations. The resulting equations were solved using Nachtsheim–Swigert iteration technique. The obtained results were conformed to existing ones, and displayed on tables and through graphs. In conclusion the investigated parameters have significant effects on the flow. Close to the boundary positive values of y is found to give rise to the familiar inflection point profile leading to the destabilization of the laminar flow. Strong injection also leads to the similar destabilization effect. Also, hall parameter m has an interesting effect on the radial and axial velocity profiles. For large values of m(>2.0), the resistive effects of the magnetic field are diminished and hence the radial and axial velocity profiles decrease with the increase of m, among others.
