Abstract
We present a Richtmyer–Meshkov instability based model for the ejected mass per unit area produced when a shockwave impinges upon a free surface with specified surface roughness amplitude and wavelength. The model is valid for sinusoidal and non-sinusoidal surface profiles and for multiple shocks, and is readily implemented in hydrodynamic computer codes. We compare the model with microscopic and macroscopic direct numerical simulations and with an extensive Sn experimental data set. The model works well for all surface profiles and captures both the time evolution and total mass for all shapes considered.
