[HTML][HTML] On shock driven jetting of liquid from non-sinusoidal surfaces into a vacuum

FJ Cherne, JE Hammerberg, MJ Andrews… - Journal of Applied …, 2015 - pubs.aip.org
Previous work employed Richtmyer-Meshkov theory to describe the development of spikes
and bubbles from shocked sinusoidal surfaces. Here, we discuss the effects of machining
different two-dimensional shaped grooves in copper and examine the resulting flow of the
material after being shocked into liquid on release. For these simulations, a high
performance molecular dynamics code, SPaSM, was used with machined grooves of kh 0=
1 and kh 0= 1/8, where 2h 0 is the peak-to-valley height of the perturbation with wavelength …
