Solution of the boundary layer flow of an Eyring-Powell non-Newtonian fluid over a linear stretching sheet by collocation method

Abstract

The aim of this article was to apply collocation method for boundary layer flow of an Eyring-Powell fluid over a stretching sheet in unbounded domain. The collocation method combined with a special technique, has been successfully applied for nonlinear equations of momentum with infinite boundary values. The solution for velocity is computed by applying the collocation method. The governing nonlinear differential equations are reduced to the ordinary differential equations by similarity transformations. The physical significance of different parameters on the velocity profile is discussed through graphical illustrations. It is noticed that the velocity increases by increasing the Eyring-Powell fluid material parameter (ε) whereas it decreases by increasing the fluid material parameter (δ).
