Effects of variable thermal conductivity on radiative MHD flow in a porous medium between two vertical wavy walls
An analysis was carried out on the effects of variable thermal conductivity on radiative MHD flow in a porous medium between two vertical wavy walls. The thermal conductivity is assumed a linear function of temperature and the fluid flow consists of two parts namely a mean and perturbed part, where the perturbed component is expressed as complex exponential series in terms of short wave length. The resultant governing equations were solved using Homotopy Analysis Method (HAM). The effects of the fluid parameters characterizing the velocity, temperature, fluid pressure, skin friction and Nusselt number were analysed and discussed.
