I heard that the shock wave was spalling off the front few cm of the liquid metal wall as a spray of jets/droplets -- the shock reflects from the vacuum interface & where the wave interfered destructively with itself, the pressure dropped to zero, and cavitation occurred. This happens in a random & uneven fashion.
- pfdietz 6y agoThat sounds very plausible. Do you have a reference I could cite?

Edit: Here's a second one that's similar (but behind a paywall). http://www.sciencedirect.com/science/article/pii/S0045793013004143 http://www.sciencedirect.com/science/article/pii/S0045793013... The preprint is here: https://arxiv.org/abs/1310.6010v2 https://arxiv.org/abs/1310.6010v2 Edit 2: Here's a better one with video frames from the experiment showing the jets. https://generalfusion.com/wp-content/uploads/2016/08/Richardson-2013-Status-of-progress-towards-acoustic-magnetized-target-fusion.pdf https://generalfusion.com/wp-content/uploads/2016/08/Richard...
