Stagnation point flow and heat transfer over a stretching or shrinking sheet in a porous medium

The steady stagnation point flow towards a stretching/shrinking sheet in a porous medium is investigated. Mathematical models are derived for stagnation point flow and heat transfer problems towards a linearly and exponentially stretching or shrinking sheet in a porous medium in the presence of magn...

Mathematical models are derived for stagnation point flow and heat transfer problems towards a linearly and exponentially stretching or shrinking sheet in a porous medium in the presence of magnetohydrodynamics, suction and slip effect at the surface. Similarity transformations are used to transform the partial differential equations into a nonlinear ordinary differential equation.
