| 摘 要： | 本文对定常不可压粘性绕流积分解法中的涡量迭代过程、涡量边界条件的提法以及压强系数的计算等方面都作了改进,使数值解更易于稳定收敛并提高精度。为了验证本文的方法,对低雷诺数下的圆柱绕流进行了计算,结果表明计算效率是高的,迭代过程是稳定的。将本文方法推广到三维流动没有原则上的困难。

| Abstract: | In order to make the numerical solution of integral rep-tresentations for steady incompressible viscous flows more accurate,stable and convergent,some improvement on the iterative procedure,he formulation of vorticity boundary condition and the method for calculating pressure coefficient has been presented in this paper,For the purpose of examination,the calculations for viscous flows about circular cylinders at low Reynolds numbers are.given.The numericalresults show that the present method is efficient and stable.No fundamental difficulties arc foreseen for extending present method to the three dimensional computations. |
