Rayleigh vs reynolds number
WebWe would like to show you a description here but the site won’t allow us. WebThe 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 …
