The Imploding Cylindrical Richtmyer-Meshkov Instability with Ideal Two-Fluid Plasma Model

The shock-interface interaction in converging flow in the presence of magnetic field is numerically studied with two-fluid plasma model. Two-fluid effect on the density field is investigated by varying Debye length: the electron and ion dynamics essentially decouple for large Debye length, and the dynamics is similar to that of a single-fluid for small Debye lengths. The influence of an initially unidirectional uniform seed magnetic field on Richtmyer-Meshkov instability in ion fluid is studied with a given Debye length.
