【摘要】 在爆轰等离子体中存在一个由化学反应放热非平衡导致的非平衡电离区。由于电子质量远小于重粒子质量,使得在电离区中电子与重粒子的能量与动量交换效率较低,这也加剧了这种非平衡特性。建立了爆轰等离子体非平衡电离区中的电子和重粒子的双流体模型,并通过该模型研究爆轰等离子体中的非平衡现象。以氢氧爆轰为例计算不同氢氧摩尔比和初始压力条件下,爆轰非平衡区中重粒子参数和电子参数的变化情况。更多还原

【Abstract】 There is a non-equilibrium ionization zone in the detonation plasma resulted from the non-equilibrium heat release of chemical reaction.Because of the low mass ratio between electron and heavy particle in the non-equilibrium ionization zone,the transfer efficiency between electron and heavy particle is low.And this enhances the non-equilibrium character.The double fluid model of electron and heavy particle is established to explore the non-equilibrium phenomenon in the detonation plasma.The parameters of electron and heavy particles in the non-equilibrium ionization zone of the oxy-hydrogen detonation are calculated by this developed model with the different oxy-hydrogen ratio and initial pressure.更多还原
