摘　　要：利用自主研发的混合网格Euler/RANS方程解算软件WoF90以及六自由度动力学与运动学方程解算程序,采用脚本语言技术实现网格的自动生成,建立了一套可用于多体分离问题的准定常Euler流动非结构网格方法。通过AEDC算例对非结构准定常Euler方程方法解决多体分离问题进行了计算研究,验证了方法的可行性。A numerical simulation strategy for the quasi- steady Euler equations simulation technology is established to solve multi- body separation problem. Script language is used to regenerate the grid and the whole flow field is parallel solved by flow solver WoF90, then the separation trajectories of the store are obtained through coupling iteration between the solution of the whole flow field and the solution of six- de- grees- of- freedom. Three major modules are integrated by script language for simulating trajectory of the store. To demonstrate the capabilities of the computational method, a well- documented test case AEDC was tested. The result shows that this numerical simulation method is feasible for research on multi- body separation simulation.
