对自由活塞双膜片激波管进行了实验和数值研究。在激波管流动序列中，当初始压力为13.3Pa时，采用氦气驱动气体，在低压管中获得了12.7km/s的激波速度。本文着重介绍了缓冲管的特性。在数值模拟中，流动被模拟为非定常、无粘和可压缩的。数值方法采用Harten-Yee二阶迎风TVD格式。通过实验和数值模拟研究了一、二级膜片破裂过程对流动特性的影响。
An experimental and numerical investigation of a free-piston double-diaphragm shock tube is conducted. In shock tube flow sequence, shock speeds up to 12.7km/s are achieved in the low pressure tube for initial pressure 13.3Pa by using helium driver gas. The present paper is described especially on characteristics of the buffer tube. In the numerical simulation, the flow is modeled as unsteady, inviscid and compressible. The numerical method employs the Harten-Yee second order upwind TVD scheme. The influence of the primary and secondary diaphragm rupture process on flow characteristics is investigated in experiment and numerical simulation.
