摘要
本文对二维非结构网格无粘流场计算的多重网格方法作了探讨。研究了非结构化多重网格的生成方法，插值算子的构造以及流场计算．以绕流ＮＡＣＡ００１２翼型无粘流场为算例，研究了多重网格法在非结构网格上的实现方法及其加速效果表明本文的方法有显著的加速收敛效果。
Two dimensional transonic flows are simulated by solving Euler equations with finite volume method numerically.Multi-Unstructured grid technique is used to accelerate the three-stages time marching convergence.Multi-Unstructured grid generation technique and interpolation method are investigated.As an example,2D transonic flows around NACA0012 airfoil are calculated with the present method.
