| 摘 要： | 多重网格法是近年发展起来的一种软加速方法，用多重网格法可明显地加快数值计算的收敛速度，且网格越密其加速效果越明显。应用多重网格法求解有钝头体的火焰稳定器管内流动问题，计算结果与试验结果比较，吻合较好。

| Abstract: | Multigrid method has been developed only in previous decade.One observes an enormous improvement of the convergence rate by such a multigrid method,resulting in a significant acceleration of the computation.The finer the grid,the larger becomes the improvement.The problem considered here is a flame stabilizator around a conical bluff body confined by a long circle pipe.The numerical results are good agreement by comparing with the experimental data |
