Computationally efficient finite element analysis of viscous flow problems
Abstract
The use of several finite element techniques for the efficient solution of problems in incompressible viscous fluid flow are developed and illustrated. Use of mesh gradation to achieve economy is demonstrated through the solution of flow in a 90 deg tee section. Automatic coarse to fine grid refinement is used to obtain details of flow in a square cavity. The use of a special finite element to model far field flow regions is shown in the solution to flow over a circular cylinder.
