非平衡等离子体运输系数的数值计算

Numerical calculation of the transport properties for no-equilibrium plasma

利用Ｃｈａｐｍａｎ－Ｅｎｓｋｏｇ方法计算了非平衡氩等离子体的运输系数及压力、温度和电子－重离子温差系数θ的影响规律．电子和重粒子被视为两种不同气体，并利用广义Ｓａｈａ公式计算等离子体成分．结果表明：非平衡态运输系数与平衡态相比有较大差别．

No-equilibrium argon plasma transport properties at low and high pressures and for various temperature-difference between electrons and heavy species are calculated by using the Chapman-Enskog method. Electrons and heavy species are treated as two different gases and a generalized Saha equation is used to calculate the plasma composition.The results show that the transport properties of no-equilibrium plasmas are far different from that of LTE plasmas.The electron electrical and thermal conductivity plays a dominant role in plasmas.
