MHD stagnation slip ow over an unsteady stretching surface in porous medium

An analysis has been carried out to study the heat transfer analysis andmhd stagnation-point ow of a viscous uid over an unsteady stretching sheet in aporous medium with slip condition. for the present problem, the governing equationsare transformed into a system of non-linear ordinary dierential equations by means ofsimilarity transformations. this system is solved both analytically by an analytic technique,namely the homotopy analysis method (ham), and numerically using a shooting methodwith runge-kutta algorithm. the inuences of the involved parameters on the ow andtemperature elds are graphically illustrated and analyzed. the results obtained by meansof both methods are compared and found in excellent agreement.
