Cavitation upon low-speed solid–liquid impact
Nature Communications, 2021 A solid hitting a liquid surface normally creates a region of high pressure at the solid-liquid contact area. Now, it is shown that for a flat-bottomed cylinder hitting a liquid at low-enough impact speed, the local pressure is sufficiently low to cause ...
