Abstract. Mathematical analysis is carried out to investigate two-dimensional flow of a viscous incompressible electrically conducting fluid near a stagnation point of a stretching or shrinking surface in a saturated porous medium. Defining equations are formulated to determine the scope of considered variables and governing partial differential equations are reduced to ordinary differential equations by using suitable similarity transformation. Numerical computation of the problem was performed by shooting iteration technique together with Runge-Kutta fourth order integration scheme. Effects of Prandtl number, permeability parameter, magnetic parameter and stretching or shrinking parameter on velocity and temperature profiles are computed and illustrated graphically, whereas numerical values of local skin-friction coefficient and local Nusselt number are presented in tabular form.
