A Model of a Source of Shock Wave Metal Ejection Based on Richtmyer–Meshkov Instability Theory

This paper provides a solution for the problem about effect of a shock wave profile on space–time distribution of velocity, density and mass of particles ejected from material free surface. It is shown that in liquid phase state of material a shock wave amplitude does not affect the ejected material mass, but is determined by the ratio β = k 2 × a 0 × Δ x ( a 0 is an initial amplitude of perturbation, k = 2π/ λ is a wave number, λ is perturbation wavelength, Δ x is a triangular shock wave pulse width).
