Keywords: unstructured cartesian grid, tree data structure, store separation

In this paper, the unstructured Cartesian grid generation method is presented. The grid generation of some configurations is performed with the tree data structure. Euler equations are solved using cell-centred finite volume method. The good agreement with experimental data shows the flexibility and accuracy of the approach. Based on the above work, a flow field numerical simulation of wing and store separation is finished using the rigid-body dynamics movement equations. This process provides a new way and tool for the more accurate solver of the unsteady flow problem.
