摘要
对 Taylor-Galerkin 广义有限元法在收敛速度和稳定性两方面作了改进,利用改进的方法,基于 Euler 方程,研究了平面跨音速叶栅流动,并与实验结果作了比较。计算结果表明,改进后的方法是跨音速计算的强有力手段。
One kind of Generalized Finite Element Method-Taylor-Galerkin has been improved on convergences of velocity and stability.Using the improved method two dimensional transonic flow in tur- bomachinery is studied.Numerical results compared with that of experiment exhibit the advantages of this method.
