Abstract / Description:Shear flow instabilities may play an important role in the dynamics of partially ionized dusty plasmas. Within a multifluid approach the onset criteria with and without electrical resistivity are derived. Long wave length modes can be stabilized by dust-neutral gas collisional momentum transport. Self-consistent numerical simulations of the multifluid plasma dynamics illustrate the nonlinear development of vortical structures in the dust, ion, and neutral velocity as well as in the magnetic field. The unstable modes lead to a significant local amplification of the magnetic field strength. Moreover, electric current sheets form that also show vortices. (C) 2002 American Institute of Physics.
