本文介绍了一种使用有限元方法的人工压缩方案。 2002 年 Zienkiewicz 银奖和获奖论文。多用途 CBS 方案以其完全显式的形式实现，以解决不可压缩流体动力学问题。值得注意的是，这里开发的方案包括分裂和速度校正。所提出的方法利用了速度校正和标准人工压缩方案的良好特性。与许多其他人工压缩方案不同，所提出的方案适用于各种网格，并给出各种雷诺数的结果。本文介绍了从所提出的方案中获得的一些基准二维和三维稳态和非稳态不可压缩流解决方案。版权所有 © 2003 约翰·威利父子有限公司
In this paper, an artificial compressibility scheme using the finite element method is introduced. 2002 Zienkiewicz Silver Medal and Prize winning paper. The multi‐purpose CBS scheme is implemented in its fully explicit form to solve incompressible fluid dynamics problems. It is important to note that the scheme developed here includes split and velocity correction. The proposed method takes advantage of good features from both velocity correction and standard artificial compressibility schemes. Unlike many other artificial compressibility schemes, the proposed one works on a variety of grids and gives results for a wide range of Reynold's numbers. The paper presents some bench mark two‐ and three‐dimensional steady and unsteady incompressible flow solutions obtained from the proposed scheme. Copyright © 2003 John Wiley & Sons, Ltd.
