翼-身-尾组合体的网格生成及 Euler 方程数值模拟

 采用代数方法快速生成翼-身-尾组合体三维O-C型贴体网格。该代数网格生成方法使用双边界法，可保证物面附近近似正交，真实地模拟了机身头部及与机翼、尾翼交界处的形状，提高了代数方法生成网格的质量。并用中心格式有限体积法求解跨声速Euler方程，以某翼-身-尾组合体模型为例，计算结果与实验符合良好。

GRID GENERATION AND EULER SOLVER FOR WING BODY TAIL CONFIGURATION

Presented here is a computational procedure for generating a mesh system and solving the Euler equation for transonic flow around a wing body tail combination . In the first part, an algebraic procedure for the generation of boundary fitted grids about wing body tail configuration is presented. The two boundary technique based on the concept of transfinite interpolation is used. As an example, an O C type grid for a model of wing body tail configuration is generated. They are of good quality. Second, an explicit time marching finite volume procedure solves the flow equation. The numerical results are in good agreement with experimental data.
