Abstract

An analysis has been carried out to study the heat transfer analysis and MHD stagnation-point .ow of a viscous .uid over an unsteady stretching sheet in a porous medium with slip condition. For the present problem, the govern- ing equations are transformed into a system of non-linear ordinary diĀ¤erential equations by means of similarity transformations. This system is solved both analytically by an analytictechnique, namely the homotopy analysis method (HAM) and numerically using a shootingmethod with Runge-Kutta algorithm. The in.uences of the involved parameters on the .ow and temperature .elds are graphically illustrated and analyzed. The results obtained bymeans of both methods are compared and found in excellent agreement.
