MHD Stagnation Point Flow and Heat Transfer of Williamson Fluid over Exponential Stretching Sheet Embedded in a Thermally Stratified Medium

摘要

Magnetohydrodynamics (MHD) stagnation point flow and heat transfer of a Williamson fluid in the direction of an exponentially stretching sheet embedded in a thermally stratified medium subject to suction present in this examination. Suitable transformations are used to convert the partial differential equations corresponding to the momentum and energy equations into highly nonlinear ordinary differential equations. The resulting equations are successfully solved by using an implicit finite difference scheme known as Keller-Box method. The results revealed that the velocity enhances with Williamson parameter and temperature reduces with stagnation parameter. The heat transfer rate at the surface increases in the presence of thermal stratification. Fluid velocity decreases with increment in magnetic parameter.
