Construction of Modified Taylor-Galerkin Finite Elements and its Application in Compressible Flow Computation

Department of Engineering Mechanics, Qinghua University, Beijing 100084, P. R. China

摘要: 本文从Tarlor-Galerkin有限元法出法,对它作了根本性的改进,构造了修正Tarlor-Galerkin算法,并用新、旧两种算法分别对亚、超音速的流场情况作了计算。计算结果表明,在达到同样计算精度的前提下,新方法较之老方法在收敛速度上有明显改进,结果是令人满意的。

Abstract: In this paper we begin with Taylor-Galerkin Finite Elements,then improve it completely and finally construct Modified Taylor-Galerkin Finite Elements.Computation is done by two methods to study two kinds of subsonic and supersonic flow field.The results show that the new one is much better than the old one.
