摘要: 用H-O网格、守恒型全位势方程、差分和隐式近似因式分解迭代算法计算绕大后掠细长翼-身组合体的可压缩流动。对AGARD-B翼-身组合体的计算表明,计算的自由流Mach数可从亚音速直到低超音速。算出的升力与力矩特性与实验数据符合较好

Abstract: The “H-O” grid is suggested in this paper to compute the compressible flow past highly swept slender wing-body combinations. Full-potential equation,finite difference method and approximate factorization iteration scheme are used. The computation for the AGARD-B wing-body shows that the code developed can be applied to the cases from subsonic up to low supersonic free streams. The computed lift and moment are in good agreement with the experimental results.

Key words: potential, flow finite-difference, throey body-wing, configurations, compressible flow
