- Abstract
The principal aim of this investigation is to study the heat transfer in axisymmetric slip flow of a MHD Powell-Eyring fluid over a radially stretching surface. The mathematical model of the physical problem solved numerically through SRM, SOR and Matlab in-built boundary value problem solver bvp4c. Results are validated by comparing with the results of the earlier studies. It shows that the proposed technique is an efficient numerical algorithm with assured convergence which serves as an alternative to common numerical methods for solving non linear boundary value problems. There is significant improvement in the rate of convergence in conjunction with SOR. The present SRM results com- pared with the previously published results of homotopy analysis method (HAM) and fourth order Runge-Kutta(RK) Method. Velocity and tem- perature profiles of the flow for various values of governing physical and fluid parameters are obtained and also the coefficient of skin friction and the local Nusselt number are calculated for the same values of the parameters. Main findings are: there is a decrease in the velocity and temperature by increasing corresponding slip parameters and the rate of skin friction increases with and decreases with b.
