Coherent density gradients in water compressed by a modulated shock wave

A shock wave propagating from liquid metal into water via a corrugated interface produces quasiperiodic perturbations in the compressed water, as determined by shadowgraphy. Theoretical analysis indicates that the shadows are caused by density gradients which occur from the coherent interaction amon...

Description
Summary:A shock wave propagating from liquid metal into water via a corrugated interface produces quasiperiodic perturbations in the compressed water, as determined by shadowgraphy. Theoretical analysis indicates that the shadows are caused by density gradients which occur from the coherent interaction among reverberating pressure waves.
