Fluid Dynamical Instabilities in Magnetized Partially Ionized Dense Dusty Plasma

Received: 05/Dec/2018, Accepted: 13/Dec/2018, Online: 31/Dec/2018 Abstract— Fluid dynamical instabilities in magnetized partially ionized dense dusty plasma are studied by taking into account relative flow between dust and neutral gas. Following Hurwitz criterion, the onset criteria for instabilities are derived for different densities of the neutral gas and dust components across the interface. It is found that in case of no significant magnetic field stabilization occurs not only due to dust neutral gas collisions but due to relative flow also. Our result might be useful in many situations of astrophysical magnetized dusty plasma namely comets and circumsteller dusty disk e.g. T-Tauri stars.
