Has anyone modelled the 'cavitation' phenomenon numerically, or performed in-depth physical tests of the phenomenon?

What would be an opposite effect where the fluid element were subjected to direct compression forces - until it 'imploded' or the like? What is this phenomenon - in gases, & liquids?

Are there any links to physical work showing the instant of vortex departure from the zone behind say a cylinder, or sudden expansion point?

Has anyone modelled these phenomena using N-S - *without* using convection-stabilisation eg. upwinding etc.?

Your comments would be very, very valuable?

Thanks, diaw...

I have located an excellent book by Brenner, on bubble dynamics & cavitation... This will help immensely...

When real fluid flows over a rear-facing step, what is observed just behind the step? Is there a small low-pressure cell there in reality? Where would I be able to find pictures of experiments at low Reynolds numbers?
