A POLYTROPIC MODEL for SPACE and LABORATORY PLASMAS DESCRIBED by BI-MAXWELLIAN ELECTRON DISTRIBUTIONS

Zhang, Yunchao; Charles, Christine; Boswell, Roderick

Description

Non-local electron energy probability functions (EEPFs) are shown to have an important effect on the thermodynamic behavior of plasmas in the context of solar wind and laboratory plasmas. A conservation relation is held for electron enthalpy and plasma potential during the electron transport. For an adiabatic system governed by non-local electron dynamics, the correlation between electron temperature and density can be approximated by a polytropic relation, with different indexes demonstrated...[Show more]
