【摘要】 文中利用对称 TVD 格式和重叠网格技术数值模拟了尖拱头部-圆柱弹身的横向喷流层流干扰流场,并利用计算结果初步研究了喷口附近流场波系结构、涡系结构及流动分离等特性,还比较了计算和实验得到的物面压力分布,两者基本吻合。更多还原

【Abstract】 The overlapping grid technique and symmetric TVD scheme are used to simulate the flow field of lateral jet interaction for the axisymmetric body.The vortex and wave structures of this flow field are shown and the topology of separation flow is given according to the computational results.The computational surface pressure distribution along jet plane is also given and well agreement with the experimental data.更多还原
