EFFECT OF RADIATION AND VISCOUS DISSIPATION ON STAGNATION-POINT FLOW OF A MICROPOLAR FLUID OVER A NONLINEARLY STRETCHING SURFACE WITH SUCTION/INJECTION

In this study we analyzed the influence of radiation and viscous dissipation on stagnation-point flow of a micropolar fluid towards a nonlinearly stretching surface with suction and injection effects. The governing equations of the flow and heat transfer are transformed in to system of nonlinear ordinary differential equations by using similarity transformation and the solved numerically using bvp4c technique with Matlab Package. The influence of non-dimensional governing parameters like radiation parameter, viscous dissipation parameter and material parameter on velocity and temperature profiles along with friction factor and heat transfer rate was discussed and presented through graphs and tables. Comparisons with the existed results are presented.
