| 摘 要： | 该文根据冲压加速器边界形状复杂的特点，利用贴体网格的弧长参数生成法，将计算域分块生成网格，而后拼接起来。用三次插值函数控制边界的网格点疏密分布，利用新方法将子块光滑拼接，为进一步研究冲压加速器的流场奠定了基础。

| Abstract: | In this paper,a curve-long parameter grid generation approach is presented and applied for ram accelerator.According to the characteristics of complicated shape bunds of ram accelerator,the computed zone is broken up into several blocks.Each block generate grid respectively,and then piece together smoothly by a new approach.The boundary grid points contribution is controlled by cubic function.This paper lay solid foundations for making further study of the flowfield of ram accelerator. |
