The Richtmyer–Meshkov instability of a shock-driven SF6 square bubble in monatomic, diatomic and polyatomic gases is investigated numerically. The focus was placed on presenting more intuitive details of the flow-fields visualizations, vorticity production, degree of thermal non-equilibrium, enstrop...
