Impact of Chemical reaction on Stagnation Point Flow of Powell Eyring Fluid: HAM Analysis

In the present study, the mathematical modelling for stagnation point flow of non-Newtonian Powell-Eyring fluid over a stretching surface is considered. The effect of thermal radiation and chemical reaction is taken into account. The non-linear governing partial equations are transformed to ordinary differential equation by using stretching similarity transformation. Homotopy analysis has been done to the reduced boundary layer equations. Numerical solutions are obtained for the velocity, temperature and concentration profiles with influence of non-Newtonian fluid parameter, radiation and chemical reaction respectively. It is found from the study that non-Newtonian fluid performs shear thinning behaviour.  Radiation enhances the temperature of non-Newtonian Powell Eyring fluid and concentration of the fluid rises as the effect of chemical reaction increases.
