| 摘 要： | 采用既有良好稳定性又有较高精度的ＳＵＰＧ有限元方法，通过数值求解涡量一流函数形式的不可压缩流ＮＳ方程组，模拟大攻角翼型在高Ｒｅ数下几种典型情况的非定常绕流流场，同时验证了ＳＵＰＧ有限元方法在求解对流占优的二维非定常对流的－扩散方程时的有铲性。

| Abstract: | By using the SUPG finite element method and a high-resolution grid system we solved 2-D incompressible Navier-Stokes equations in vorticity-streamfunction variables at high Reynolds numbers. Viscous flows past a NACA0012 airfoil with a constant angular speed were presented in this paper. It has been shown that the SUPG FEM is feasible for the simulation of the convection dominated 2-D unsteady viscous flows. |
