摘要

摘要: 用流体网格法（Fluid in Cell）对气体在锐角几何条件下的压缩做了二维轴对称不定常流体动力学数值模拟。研究了压缩室内气体的侧向及轴向压缩规律；讨论了导出管中高温等离子体的流动特性；给出了等离子体参数的空间分布及随时间变化的定量数据；研究了结构几何尺寸及气体介质初始密度对最终参数的影响，并与文献报道的实验数据作了比较，结果基本符合。

Abstract: In this paper, the Fluid in Cell method is used to numerically simulate two-dimensional, axisymmetric and time-dependent motion for the compressible flow of a fluid which was in the sharp angle regions between the fly-plate and the wall of the compression-chamber. Compression properties of the fluid in the gas compression chamber, and motion properties of the high-temperature plasma in the outlet-tube, were studied and discussed. The distributions of plasmas variables were obtained, which were comprised with reported experimental data.
