ElectronEnergyLossFromElastic
Electron energy loss term for elastic collisions using Townsend coefficient (Densities must be in logarithmic form)
Overview
ElectronEnergyLossFromElastic calculates the electron energy loss from elastic collisions using Townsend coefficients for electrons in logarithmic form. ElectronEnergyLossFromElastic assumes the electrostatic approximation for the electric field.
Electron energy loss from elastic collisions can be described as
Where is the loss term of the electron mean energy density, is the electron flux, is the Townsend coefficient for elastic electron-neutral collisions, is the mass of the electrons, is the mass of the neutral species, is the electron density, is the electron mean energy density, is the mobility coefficient, is the diffusion coefficient, and is the potential. When converting the density to logarithmic form and applying a scaling factor of the mesh, the strong form for ElectronEnergyLossFromElastic is defined as
Where is the molar density of the species in logarithmic form and is the scaling factor of the mesh.
commentnote
When coupling Zapdos with CRANE, ElectronEnergyLossFromElastic serves the same function as CRANE's ADEEDFElasticTownsendLog.
