2D Fluid Simulations of Hall Thrusters Reveal Kelvin-Helmholtz Waves
Graduate Student Aaron Knoll has developed 2D z-theta simulations to
capture the development of high frequency waves which propagate along
the azimuthal direction of Hall discharges. These instabilities
are believed to be important in the establishment of the cross-field
electron current, which is anomalously high in these devices.
