| 摘 要： | 用一般理论计算激波管参数，由于激波的衰减不可避免以及一定压力下的气体是非理想气体，故会有不小误差。本分别考虑了衰减和真实气体效应这两种对激波速度有影响的因素，对一种具有良好压力平台的激波管（驱动气体为Ｈ２，被驱动气体为ＣＯ２）中的激波速度进行了计算。首先采用考虑真实气体效应的理论，计算破膜后形成的初始激波速度；在激波沿管运行理论不能准确计算的阶段，采用由实验得出的激波衰减公式进行计算。计算结果与

| Abstract: | The theoretical calculation of the shock wave speed in a shock tube is not accurate because of the presence of real gas effect and shock attenuation. In this paper, the speed of shock wave in the shock tube (H 2 is used as a driving gas and CO 2 as a driven gas) is calculated by two special steps. The initial shock wave speed is calculated by theory , while the shock wave goes along the shock tube, and calculated by a shock wave attenuation formula which comes from experiment. The result of the calculation is coincident with that of the experiment, which can be used as a reference for the shock tube design. |
