2D HE-thruster Liu2010

  • Boris-leapfrog time integration with cell volweight mean deposition on a 2D domain

  • external magnetic field in radial direction (algebraic expression)

    PIC-AlgebraicExternalField = 2 ! 2: 2D Liu 2010 magnetic + electric field PIC-AlgebraicExternalFieldDelta = 2 ! Integer

  • MCC with variable background gas distribution from .h5 file

    Particles-BGGas-UseDistribution = T Particles-MacroscopicRestart-Filename = pre-BGGas/2D_HET_Liu2010_DSMCState_000.0007000000.h5

  • SEE model with variable electron bulk temperature (which changes the behaviour of the SEE yield)

    • Morozov (2004) with variable SEE yield depending on electron impact properties

      Part-Boundary3-SurfaceModel = 8 ! SEE-E (bombarding ions are reflected, e- on dielectric materials is considered for secondary e- emission with different probabilities for different outcomes) by Morozov2004 Part-Species2-PartBound3-ResultSpec = 2 ! impacting e- (Part-Spec is 2) results in emission of e- (ResultSpec is 2) Part-SurfaceModel-SEE-Te = 5.80226250308285e5 ! = 50 eV / Electron temperature in K: 5.80226250308285e5 K corresponds to 50 eV, 1.16045250061657e4 K corresponds to 1 eV

    • with variable electron bulk temperature (determined globally)

      Part-SurfaceModel-SEE-Te-automatic = T ! Instead of using a fixed bulk electron temperature, determine the global temperature of the defined species (default is False). Note that Part-SurfaceModel-SEE-Te is used as initial value. Part-SurfaceModel-SEE-Te-Spec = 2 ! For automatic bulk Te determination, state the species ID of the electrons

  • Neutralization emission BC via keeping the exiting charge at the right BC zero over time (averged)

    Part-Species2-Init2-SpaceIC = 2D_Liu2010_neutralization

    or by enforcing a neutral boundary layer at the right exit by emitting electrons if there is an ion surplus in the first row of elements

    Part-Species2-Init2-SpaceIC = 2D_Liu2010_neutralization_Szabo
