不同初始压力下氟利昂-空气混合气体爆炸反应参数的数值计算

为研究氟利昂-空气混合气体的爆炸特征，本文采用基于体系达到化学平衡，其自由能最小原理的数值计算方法，计算了不同氟利昂含量的氟利昂．空气混合气体在不同初始压力下的反应温度和压力。结果表明，氟利昂-空气混合气体的反应温度和压力，随着初始压力的升高而增大，在初始压力一定时，氟利昂含量为20％的混合气体反应温度和压力最大。

Numerical Calculation of Detonation Reaction Parameters of CHClF2-Air Mixed Gas in Different Initial Pressures

To investigate the detonation character of CHClF_2-air mixed gas,a numerical calculation method based on the theory,which the free energy is considered to be the minimum value at the equilibrium state after the reaction,was used to calculate the reaction parameters of mixed gas. The reaction temperature and pressure of the mixed gas were calculated in the different initial pressure and concentration. The results show that the reaction pressure and temperature increase along with initial pressure. The reaction temperature and pressure of mixed gas including 20 percent CHClF_2 are the maximal.
