Abstract

A procedure for solving the Navier-Stokes equations for the steady three-dimensional flow of a non-newtonian fluid within a finite width slider thrust bearing is described. The method uses a finite difference approach together with a technique known as SIMPLE (semi-implicit method for pressure-linked equations) which has now become well established in the field of computational fluid dynamics. The concept of “effective viscosity”, used to describe the non-linear dependence of shear stress on shear rate, is also employed. To illustrate the capabilities of the procedure, results are presented for a wide range of non-linearity factors and these are compared with results from another source.
