Investigation of townsend energy factor and drift velocity for air in terms of L, G & E P

Abstract EN

In this work had been determine the Townsend's energy factor KT and the electron drift velocity in terms of electron mean free path L in unit of pressure, the energy loss factor G and the applied electric field to the gas pressure ratio at 300 oK in air.

The obtain transport coefficients by solved numerically transport equation solution and had be fed to the derived equations.

The obtained results had be graphically draw as a function for its variables, which appeared a good agreement with published experimental da.
