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 feasible and effective.
