Numerical Study of the Three-dimensional Stagnation Point Flow of Non-Newtonian power-law fluid

Abstract

 In the present task, we consider the motion of a steady, laminar three-dimensional stagnant boundary-layer (3D BL) flow of non-Newtonian Ostwald-de-Waele model. The governing partial-differential system with appropriate boundary conditions are transformed in to couple nonlinear  ordinary-differential systems using surface similarity transformations. These equations contain two physical parameters: three-dimensionality parameter and power index. The resulting system are solved by numerical methods (i.e. shooting technique). The various effects of physical parameter on the velocity field and wall shear stress are analyzed through graphs and tables.
