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。
Multi-grid method is a soft acceleration method developed in recent years. The multi-grid method can obviously accelerate the convergence of numerical calculation, and the more dense the grid is, the more obvious its acceleration effect is. The multi-grid method is used to solve the problem of flow in a flame stabilizer pipe with a blunt body. The calculated results are in good agreement with the experimental results.
