| 摘 要： | 采用非结构重叠网格Euler方程的CFD方法数值模拟了外挂投放。该方法在重叠网格"挖洞"时,以"离壁面距离"为挖洞判据;在建立重叠区域插值关系时,对Neighbor to Neighbor(N2N)和Alternating Digital Tree(ADT)两种方法的效率进行了比较。采用机翼/挂架/带舵外挂物模型开展了验证计算。在此基础上,完成了某飞行器外挂投放的初步计算。

| Abstract: | An overset unstructured grid using the three dimensional Euler equations is applied to simulate the store separation problems.The distance to walls criterion is used in the automatic hole-cutting procedure.The searching efficiency of the Neighbor to Neighbor(N2N)and Alternating Digital Tree(ADT)are compared as well during the procedure.This method is used for computing the trajectories of the Wing/Pylon/Finned-Store configuration,and compared with the experimental data.And a complex separation problem is so... |
