| 摘 要： | 本文提出约束迭代法以改进不可压分离流计算中的迭代收敛性。在每个时间步的迭代中,对涡量传输方程的边界涡量,预先进行近似估计。因此它相当于一种隐式的边值算法。 两个翼型的算例表明,约束迭代法具有高的收敛速度。由于无需寻找最优松弛参数,因而节省人力,便于使用。

| Abstract: | Constraint iteration,based on an approximate estimation of the surface vorticity before solving vorticity transport equation in each iteration,is proposed to improve the convergence.Examples show that constraint iteration not only has a high convergence rate,but also saves manual labour in searching for optimal relaxation parameters as is done in relaxation iteration technique. |
