Abstract

An important class of fluids, namely generalized Newtonian fluids, have been the subject of considerable research in the area of petroleum engineering and bio- mechanics. This contribution deals with a comparison between velocity-vorticity formulation used in the Boundary element method and the Finite difference method. Both methods decompose material properties into its constant contribution. The formulation is applied in its two dimensional form for flow in a driven cavity, believed to be a widely used benchmark problem for a wide array of fluid dynamics problem. Introduction A number of fluids are used within process engineering, among them fluids which do not obey Newton's viscous law, the so called non Newtonian flu
