Dust Particle Charge-up in a Corona Discharge

April 18th, 2018 dust-particle-chargeup-plasma-corona

This example demonstrates charge-up of initially charge-free dust particles as they move through a pin-corona plasma. Two sets of particles move through the corona with different initial velocities. The dust particles are subject to Lorentz forcing in the electric field and their resulting trajectories are compared. The macroscopic particle dynamics is modeled in VizGrain and coupled to a background plasma solution modeled in VizGlow. The 2D planar pin geometry and mesh is shown in Figure […]
