Abstract
Comprehensive numerical solutions of the steady state incompressible v iscous flow over a three-dimensional backward-facing step up to Re = 8 00 are presented. The results are obtained by the least-squares finit e element method (LSFEM) which is based on the velocity-pressure-vorti city formulation. The computed model is of the same size as that of Ar maly's experiment. Three-dimensional phenomena are observed even at lo w Reynolds number. The calculated values of the primary reattachment l ength are in good agreement with experimental results.
