对感应热等离子体进行了建模，以研究化学非平衡对解离和电离的影响。对大气压下的氩氧等离子体进行了计算。通过求解二维模型得到了热流体场和浓度场。这个公式是用Chapman-Enskog方法的高阶近似来估计输运性质的。与平衡模型的偏差表明，氩氧诱导等离子体在解离和电离时应被视为非平衡态。为热等离子体加工新材料的合理设计提供了理论指导。
Modeling of induction thermal plasmas has been performed to investigate chemically non-equilibrium effect for dissociation and ionization. Computations were carried out for argon–oxygen plasmas under atmospheric pressure. The thermofluid and concentration fields were obtained by solving two-dimensional modeling. This formulation was presented using higher-order approximation of the Chapman–Enskog method for the estimation of transport properties. A deviation from the equilibrium model indicates that argon–oxygen induction plasmas should be treated as non-equilibrium for dissociation and ionization. The present modeling would give the guidance for the rational design of new material processing using thermal plasmas.
