MHD Stagnation-Point Flow and Heat Transfer over an Exponentially Stretching/Shrinking Vertical Permeable Cylinder

Abstract:

The present literature analyzes the MHD stagnation-point flow of an incompressible fluidover an exponentially stretching/shrinking permeable cylinder in the presence of a transverse magnetic field, and suction/injection. The governing partial differential equations in cylindrical form aretransformed into coupled ordinary differential equations (ODEs) using suitable similarity transformations. These ODEs are solved using optimal homotopy analysis method (OHAM) via Mathematicasoftware BVPh 2.0 package. The effects of various governing parameters such as curvature parameter, magnetic parameter, wall transpiration parameter, velocity ratio parameter and Prandtl number onvelocity and temperature profiles have also been examined graphically.
