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。
Several grid generation methods and their numerical simulation of flow field are discussed. A multiblock patched grid for a modern twin vertical tail fighter and a domain decomposition solution of the Euler equation are given. A zonal patched grid for a wing with control surface deflection and Euler solution for the flow around the wing are also given. The overlapping grid method, unstructured grid method and adaptive Caresian grid method are discussed for a two dimensional multielement airfoil.
