摘　　要：利用对称TVD格式和重叠网格技术数值求解层流N-S方程,模拟了翼身组合体构形的横向喷流干扰流场,研究了该流场的涡系结构、波系结构及流动分离等流场特性,讨论了干扰效应对气动性能的影响,计算了干扰力放大因子和干扰力矩系数,其结果与实验结果基本相符。By the use of the overlapping grid technique and symmetric TVD scheme, the laminar flow N-S equation was solved and the flow field of lateral jet interaction for a missile-like wing-body configuration was simulated. The vortex and wave structures of this flow field were shown and the topology of separation flow was given according to the computational results. The interaction effects on aerodynamic characteristic were studied. The computational amplification factor and the moment coefficient of interaction were also given and they are basically in agreement with the experimental data.
