Reactive Richtmyer–Meshkov instability under various Mach numbers

Richtmyer–Meshkov instability (RMI) at a single-mode interface separating an inert gas (N $_2$ ) and a reactive gas mixture (H $_2$ /O $_2$ /Xe) under reshock conditions is numerically investigated using a newly developed compressible reactive Navier–Stokes solver. The solver employs the Kéromnès mechanism (10 species, 21 reactions) for combustion modelling and a dual-flux algorithm to suppress numerical oscillations at material interfaces, demonstrating high accuracy across a wide range of benc
