摘要讨论了多种网格生成方法及其流场的数值模拟。给出了一种生成现代双立尾战斗机外
形的分区对接网格和 Euler 方程分区解。给出了一种带副翼偏转的三维机翼分区网格及绕流的
Euler 方程解。以二维多段翼型为对象分别讨论了分区重叠结构网格方法、非结构网格方法和自
适应的笛卡尔网格法。

Abstract Several grid generation m ethods and their num erical simulation of flow field are dis
cussed. A m ultiblock patched grid fo r a modern tw in vertical tail figh ter and a dom ain po
sition so lution of the Euler equation are given. A zonal patched grid fo r a w ing w ith contro l sur
face deflection and Euler so lution fo r the flow around the w ing are also given. T he overlapp ing
grid m ethod, unstructured grid m ethod and adap tive Caresian grid m ethod are discussed fo r a
two dimensional m ultielem ent airfo il.
Key words zonal patched grid, zonal overlapp ing grid, unstructured grid, adap tive Cartesian
grid, Euler equation
