In a typical Richtmyer-Meshkov experiment a fast moving flat shock strikes a stationary
perturbed interface between fluids A and B creating a transmitted and a reflected shock, both …

摘要当强冲击波从金属自由面反射时通常会发生微喷射现象, 气体环境下,
喷射颗粒将与气体相互作用而形成物质混合. 微喷射与混合是战略武器研究中的关键和难点问题 …

When a shock wave reaches the free surface of a material with surface asperities, particles
can be ejected from the surface. The mass and velocity of the ejecta depend on the strength …

The transport process of micro-ejecta in reactive gases has recently attracted research
attention and interest. Here, we investigate the interaction between shock-induced ejecta of …

Flow instabilities play important roles in a wide range of engineering, geophysical, and
astrophysical flows, ranging from supernova explosion in crab nebula, formation of clouds in …

We discuss the processes controlling ejecta particle production and breakup, as a result of
shock wave compression of condensed matter and in broader contexts. We present analytic …
