An RBF Solution to a Stagnation Point Flow Towards a Stretching Surface with Heat Generation

In this paper, we propose radial basis function (RBF) to solve nonlinear momentum and energy equations obtained from modeling steady laminar flow through a porous medium of an incompressible viscous conducting fluid imping- ing on a permeable stretching surface with heat generation. This flow impinges normal to a plane wall with heat transfer. Our reports consist of the effect of the porosity of the medium, the surface stretching velocity, and the heat generation/absorption coefficient on both the flow and heat transfer. A simple solution by using collocation points over the almost whole domain (0, ∞) is obtaind. We apply this method through the definite integration process and satisfy the infinity boundary condition by using Gaussian RBF. Index Terms—Stagnation point flow; Heat transfer; Porous medium; Radial basis function; Gaussian RBF.
