摘　　要：应用隐式有限体积 TVD 格式数值模拟了弹丸底排流-侧喷流共同干扰流场,研究了底排流动对于弹丸侧喷干扰流场的影响,分析了弹丸底排-侧喷共同干扰流场的特性,表明底排流具有添质加能和引射两种相反的作用,发现底排流减弱了侧喷流对弹底流动的影响,研究结果对于底排-火箭复合增程技术具有重要的参考价值。Implicit finite volume TVD schemes are applied to numerically simulate unitied interaction flowfield over projectile with lateral jets and base bleed.The interaction effect of base bleed to lateral jets flow is studied.Some laws of interaction flow of base bleed and lateral jets are obtained.The base bleed has two contrary action of providing energy and ejection,and it can weaken the effect of lateral jet upon base flow.The results are very important for the study of projectile with lateral rocket boosters ...
