摘要
提出了一种不依赖于背景网格的新型阵面推进法,采用结构数组与邻接表相结合的数据结构,大大提高了查找、删除操作效率.应用本方法和有限体积TVD格式对模拟弹流场进行模拟,并与实验照片进行了对照,获得了满意的结果.
A new advancing-front method which is independent of the background is introduced. A new data structure which combines structured array and adjacency list is applied in this method to increase the efficiency of search and deletion greatly. The method and the finite volume TVD scheme are used to simulate the experimental projectiles with high speed, and the good results in accordance with the experimental photos are obtained.
