HagelaarElectronAdvectionBC
Kinetic advective electron boundary condition (Based on Hagelaar et al. (2000))
Overview
HagelaarElectronAdvectionBC is an electric field driven outflow boundary condition.
The electric field driven outflow is defined as
Where is the outflow normal to the boundary, is the normal vector of the boundary, is the mobility coefficient, is the electron density, and is the electric field. is defined such that the outflow is only defined when the drift velocity is directed towards the wall and zero otherwise. is defined as the fraction of particles reflected by the surface. When converting the density to log form and applying a scaling factor of the mesh, the strong form for HagelaarElectronAdvectionBC is defined as
Where is the molar density of the species in log form and is the scaling factor of the mesh.
