ElectronEnergyTermRate

Electron energy loss term for inelastic collisions using reaction rate coefficients. Threshold energy is the energy lost in Volts in a single collision (Densities must be in logarithmic form)

Overview

ElectronEnergyTermRate calculates the electron energy loss from elastic collisions using reaction rate coefficients for electrons in logarithmic form.

Electron energy loss from elastic collisions can be described as

$var element = document.getElementById("moose-equation-e46d3aa1-8ee1-4247-94d0-b789f3f1dece");katex.render("S_\\text{Loss} = k \\epsilon n_{e} n_{j}", element, {displayMode:true,throwOnError:false});$

Where $var element = document.getElementById("moose-equation-429e1c81-e716-4725-be4e-2183c7c300b5");katex.render("S_\\text{Loss}", element, {displayMode:false,throwOnError:false});$ is the loss term of the electron mean energy density, $var element = document.getElementById("moose-equation-e32df117-54e7-46a1-9622-7d379c7e72f2");katex.render("k", element, {displayMode:false,throwOnError:false});$ is the reaction rate coefficient, $var element = document.getElementById("moose-equation-a1709465-71a6-4501-8524-56b64a964f55");katex.render("n_{e}", element, {displayMode:false,throwOnError:false});$ is the electron density, $var element = document.getElementById("moose-equation-3fdf7d5d-678c-40cf-8da2-05071b6ecd67");katex.render("n_{j}", element, {displayMode:false,throwOnError:false});$ is the colliding species density, and $var element = document.getElementById("moose-equation-5855c831-3f4c-4034-a6e0-f20fd0a684ab");katex.render("\\epsilon", element, {displayMode:false,throwOnError:false});$ the electron energy lost in the collision. When converting the density to logarithmic form and applying a scaling factor of the mesh, the strong form for ElectronEnergyTermRate is defined as

$var element = document.getElementById("moose-equation-1e8a550a-6671-4d9b-b4d5-9bb671cca6c1");katex.render("S_\\text{Loss} = k \\epsilon \\exp(N_{e}) \\exp(N_{j})", element, {displayMode:true,throwOnError:false});$

Where $var element = document.getElementById("moose-equation-d6be2aae-b1cc-47f4-92df-5fecac1e9e78");katex.render("N_{j}", element, {displayMode:false,throwOnError:false});$ is the molar density of the species in logarithmic form and $var element = document.getElementById("moose-equation-75398e51-cf2d-4095-82dc-f566ae8701b6");katex.render("l_{c}", element, {displayMode:false,throwOnError:false});$ is the scaling factor of the mesh.

note

When coupling Zapdos with CRANE, ElectronEnergyTermRate serves the same function as CRANE's ADEEDFEnergyLog.

warning:Untested Class

The ElectronEnergyTermRate does not have a formalized test, yet. For this reason, users should be aware of unforeseen bugs when using ElectronEnergyTermRate.
