Heat transfer analysis of the steady flow of a fourth grade fluid

This paper deals with the influence of heat transfer on the flow of a fourth grade fluid past a porous plate. The heat transfer analysis has been carried out for the prescribed temperature. The series solution is first developed using homotopy analysis method (HAM) and then analyzed for its convergence. The obtained velocity profile is compared with the existing exact solution of the same flow problem for a second grade fluid. It is found that HAM results are in excellent agreement with the exact solution. Finally, the velocity and temperature profiles are plotted and discussed. It is noted from the solution series that the results in the case of injection does not exist.
