Simulations of Kelvin-Helmholtz modes in partially ionized dusty plasmas comparing different charge numbers, charge polarities, and masses of the dust

Abstract

Results of multifluid simulations of Kelvin-Helmholtz modes in partially ionized, dusty plasmas are presented assuming different masses and charges of the dust. The results show a stabilizing effect for more massive dust grains and indicate a destabilizing effect for higher charge numbers. No significant dependence on the charge polarity of the dust was found. © 2006 American Institute of Physics.
