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.
