Transport coefficients of a weakly ionized plasma with nonextensive particles

摘要

The transport coefficients of a weakly ionized plasma are studied in the non-extensive statistics framework using the Boltzmann equation. We find that some of these transport coefficients depend on the nonextensive parameter, q. It is seen that, in the case of qs smaller than one (superthermal particles), the diffusion coefficient is meaningful only in the range 3/5 q 1 so that it decreases with increasing q. Also, for q 1 (sub-thermal particles), the diffusion coefficient decreases as q increases. On the other hand, the thermal conductivity is meaningful just in the range of 5/7 q 1. In addition, it is observed that the increase in q gives rise to the decrease in the thermal conductivity value in both superthermal and sub-thermal particles. Furthermore, the electrical conductivity is independent of the q parameter in contrast to the fully ionized plasma [Z. Ebne Abbasi and A. Esfandyari-Kalejahi, Phys. Plasmas 23, 073112 (2016)]. Finally, we compare our results to the previous ones based on Kappa distributed electrons and ions [L. Wang and J. Du, Phys. Plasmas 24, 102305 (2017)]. Published under license by AIP Publishing.
