摘要：

In this paper the development and behaviour of a new finite element algorithm for viscous incompressible flow is presented. The stability and background theory are discussed and the numerical performance is considered for some benchmark problems. The Taylor–Galerkin approach naturally leads to a time‐stepping algorithm which is shown to perform well for a wide range of Reynolds numbers (1 ⩽ Re ⩽ 400). Various modifications to the algorithm are investigated, particularly with respect to their effects on stability and accuracy. Copyright © 1990 John Wiley & Sons, Ltd
