| 摘 要： | Based on the Chapman-Enskog theory, we calculate the electrical conductivity of non-equilibrium air plasma in the two-temperature model. We consider different degrees of non-equilibrium, which is defined by the ratio of electronic temperature to heavy particles temperature. The method of computing the composition of air plasma is demonstrated. After calculating the electrical conductivity from electron temperature 1000 K to 15000K, the present result is compared with Murphy＇s study Plasma Chem. Plasma Process 15 （1994） 279] for equilibrium case. All the calculation is completed at atmospheric pressure. The present results may have potential applications in numerical calculation of non-equilibrium air plasma.

| Abstract: | Based on the Chapman--Enskog theory, we calculate the electrical conductivity of non-equilibrium air plasma in the two-temperature model. We consider different degrees of non-equilibrium, which is defined by the ratio of electronic temperature to heavy particles temperature. The method of computing the composition of air plasma is demonstrated. After calculating the electrical conductivity from electron temperature 1000K to 15000K, the present result is compared with Murphy's study Plasma Chem. Plasma Process 15 (1994) 279] for equilibrium case. All the calculation is completed atatmospheric pressure. The present results may have potential applications in numerical calculation of non-equilibrium air plasma. |
