| 摘 要： | 针对非定常的气相强爆轰过程，建立了气相爆轰的理论计算模型，结合C-J理论和多方气体物态方程，对乙炔-氧气混合气体的强爆轰参数进行了理论估算，并在激波管中开展了化学计量比的乙炔-氧气混合气体的强爆轰实验。对比研究表明：爆速的理论估算值与实验值符合较好，证实了采用C-J理论估算气相强爆轰参数的可行性，计算数据具有一定的参考价值。

| Abstract: | Based on the C-J theory and polytropic gas equation of state,a simple physical model is developed to calculate the parameters of overdriven detonation wave for C2H2-O2 mixture with a stoichiometric ratio.The overdriven detonation experiments are also performed in a shock tube using a high speed digital camera and six piezoelectric sensors.The calculated overdriven detonation velocity is in agreement with the experimental value.Therefore,the overdriven detonation parameters obtained by this method are feasib... |
