Electron Transport Parameters in Hydrogen-Argon Mixtures

摘要

The Boltzmann transport equation is solved by using two term approximation for binary gases. This method of solution is used to calculate the electron energy distribution function and electron swarm parameters of electron accelerated by d.c. electric field in a mixture of H2 - Ar were calculated in the range O.O1Td ≤ E/N ≤ 1.0 Td (lTd= 10~(-17) V.cm~2) at temperature 300K. These parameters namely are: electron drift velocity, mean electron energy, characteristic energy, and electron mobility and diffusion coefficient. The calculated distribution function is found to be non-maxwillian that has energy variation which reflects the import electron molecule energy exchange processes. The electron drift velocities as a function of gas number density of the mixture are studied.
