本文提出了高雷诺数下流体非定常粘性流动的有限元分析方法。该方法是基于显式数值积分方案的时间和使用三节点三角形有限元。为了公式的方便，考虑了轻微的可压缩性。对于显式格式，成功地采用了选择集总两步法。计算了圆柱绕流后的旋涡脱落，并与常规实验结果进行了比较。两种方案的比较结果一致。
This paper presents the finite element method for the analysis of unsteady viscous flow of fluid at high Reynolds numbers. The method is based on the explicit numerical integration scheme in time and uses three node triangular finite elements. For the convenience of the formulation, slight compressibility is considered. For the explicit scheme, the selective lumping two step scheme has been successfully employed. Vortex shedding behind a cylinder has been computed and compared with the conventional experimental results. The results agree favourably when both schemes are compared.
