WebbThe Richtmyer-Meshkov (RM) instability occurs when a shock passes through a perturbed interface separating fluids of different densities. Similarly, RM instabilities may also occur when a perturbed interface between two incompressible fluids of different density is impulsively accelerated. WebbThe low frequency stability of a dusty plasma with a nonuniform mass and charge distribution of the dust component is studied. It is shown that the inverse stratification of the dust mass density in a gravitational field may lead to a Rayleigh–Taylor-like instability. In the nonlinear regime this instability can produce an incompressible flow pattern of …
