HagelaarIonDiffusionBC
Kinetic electron boundary condition (Based on Hagelaar et al. (2000))
Overview
HagelaarIonDiffusionBC is a thermal outflow boundary condition.
The thermal driven outflow is defined as
Where is the outflow normal to the boundary, is the normal vector of the boundary, is the ion density, is the thermal velocity of the ions, is the Boltzmann constant, and is the gas temperature. 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 HagelaarIonDiffusionBC is defined as
Where is the molar density of the species in log form and is the scaling factor of the mesh.

# This example sets up a simple varying-voltage discharge with a
# dielectric at the right boundary.
#
# Two charged particle species are considered, creatively named 'pos'
# and 'neg'. They both have the same initial conditions and boundary
# conditions; the only difference is their charge.
# As the voltage varies, the particle flux to the right boundary
# (including both advection and diffusion) will switch polarity and
# the surface charge will become increasingly negative or positive.
#
# The left boundary is a driven electrode with a sinusoidal waveform.
# A dielectric boundary condition including surface charge accumulation
# is included on the right boundary.
#
# Note that without surface charge the electric field across both
# boundaries should be identical since their permittivities are
# both set to the same value.
# Surface charge shields the electric field in the gas region,
# preventing strong field buildup.
