不同初始温度下H_2/O_2混合物等离子体的演化

Evolution of H_2/O_2 mixture plasma under different initial temperatures

本文对不同初始温度下,H2/O2混合物等离子体中主要粒子随时间发展的演化规律进行了数值模拟,得到了放电后等离子体中主要带电粒子和中性粒子密度随时间的变化规律.计算结果表明,H2/O2混合物等离子体中主要活性粒子密度随时间的增加减小,化学反应达到平衡所需的时间随初始温度升高逐渐减少.

This paper presents a numerical simulation of the evolution of the main particles in H2/O2 mixture plasma under different initial temperature,and gives the time-variation laws of the density of the main charged and neutral particles in plasma after discharge begins.The results show that the density of main active particles in H2/O2 mixture plasma is reduced with time,and the required time for the equilibrium of chemical reactions reduces with increasing initial temperature.
