The rapid dynamics of vapor bubbles, the so-called cavitation bubbles, in confined geometries may lead to surprisingly rich dynamics. The example presented here in Fig. 1 a shows a cavitation bubble expanding and collapsing inside a liquid droplet, which creates two high-speed liquid jets shooting upwards. The primary jet is formed during the initial bubble expansion and collapse, and the secondary cylindrical jet forms when the bubble rebounds, i.e., after the collapse. The top picture… CONTINUE READING
