Multiple steady state co-rotating dust vortices in streaming plasma

Abstract: The 2D hydrodynamic model for a dust cloud confined in an axisymmetric toroidal system volumetrically driven by an unbounded streaming plasma is further extended systematically for different aspect-ratio of the bounded dust domain and a wide range of the kinematic viscosity. This work has demonstrated the interplay between inertial and diffusive transport processes for the structural changes of steady dust flow from symmetric into asymmetric nature in higher Reynolds number (Re) regimes where flow streamlines … Show more

“…We assume that the bounded dust cloud/cluster is driven by both the driving fields, i.e., ω s from the shear nature of the background ion-drag and ω BP from the shear E a derived in equation (13). As in the previous work [14], ions are considered streaming downward throughout the dust cloud, having a monotonic shear profile given by a single natural mode of the cartesian plane as given by,…”
