Abstract

We used EEDF software package program to solve Boltzmann equation to calculate the electron energy distribution function in (50% SF6 – 50% Xe) mixture. The calculations are achieved under a steady state electric field using the classical two - term approximation. The electron energy distribution function (EEDF) and the corresponding transport coefficients (mean electron energy, characteristic energy, mobility of electron, diffusion coefficient, and drift velocity) for constant and various electron concentrations are calculated and graphically represented. It is found that variations of electron concentration have a significant effect on transport coefficients of the mixture. The work is in a well agreement with previously experimental and computational researches.

Highlights

  • energy distribution function (EEDF) has a substantial role in plasma modeling due to it need for computation the reaction rates for electron collision reactions [1,2]

  • In thermodynamic equilibrium the EEDF has a Maxwellian shape if the ionization degree is high because electron – electron collisions drive the distribution towards a Maxwellian [6]

  • The influence of the electron distribution function (EEDF) vs. the mean electron energy for different ratio of electric field to the gas density (E/N) in mentioned mixture is shown in figure (1)

Summary

Introduction

EEDF has a substantial role in plasma modeling due to it need for computation the reaction rates for electron collision reactions [1,2]. “NUMERICAL CALCULATIONS OF THE ELECTRON ENERGY DISTRIBUTION FUNCTION IN (50% SF6 - 50 % Xe) MIXTURE WITH CORRESPONDING TRANSPORT PARAMETERS.” International Journal of Research - Granthaalayah, 7(3), 97-104. This program gives results of the kinetic and transport coefficients of plasma in the mixture of gases by numerically solving Boltzmann equation of EEDF in low – ionized plasma in an electric field.
