Numerical Study on the Single-Mode Richtmyer-Meshkov Instability in a Cylindrical Geometry
Evolution of a single-mode air/SF6 interface accelerated by a converging shock is investigated numerically. For comparison, a planar case with the same perturbation amplitude and wavelength as well as the initial...

On the Evolution of Reshocked Gas Cylinder Under Planar and Converging Shock Conditions
Richtmyer-Meshkov instability (RMI) [1, 2] arises when an interface separating two fluids with different densities is impacted by an impulsive acceleration. Due to the baroclinic mechanism, the initial perturb...
