Effect of homogeneous-heterogeneous reactions in stagnation point flow of third grade fluid past a variable thickness stretching sheet

Present work addresses the stagnation point flow of third grade fluid past a variable thicked stretching sheet. Homogeneous and heterogeneous reactions are considered. Impact of thermal radiation and variable wall temperature is studied here. System of nonlinear ordinary differential equations is obtained by suitable transformations. Convergence of series solutions is achieved. Fluid flow, temperature and concentration field are deliberated through graphs for different parameters. It is seen that velocity and temperature fields increase for higher shape parameter. Increasing values of homogeneous parameter decline the concentration profile. Velocity profile enhances when wall thickness parameter and ratio of free stream velocity and stretching velocity are increased.
