Abstract: The numerical simulation of axisymmetric two-dimensional shock tube is studied, which has a conical convergent section, and its driving gas is the hot product of hydrogen oxygen detonation. Finite volume TVD scheme is adopted and the mesh is local orthogonal. The primitive equations are Euler's equations of multi-component flow. The new method of eliminating numerical oscillation at the interface of two materials is extended to two dimensions (2D). The mechanical character of this shock tube is analyzed.

Key words: shock tube, conical convergent section, detonation, finite volume TVD scheme

摘要： 对由前向爆轰产生驱动气体并具有局部锥形收缩截面的轴对称激波管利用两相常比热完全气体的欧拉方程组和有限体积TVD格式在局部正交的网格上进行了二维数值模拟。将消除两种介质界面处数值振荡的新方法成功地推广到二维情况。分析了该激波管的力学特性。
