Collapse of Non-Axisymmetric Cavities
Oscar R. Enriquez, Ivo R. Peters, Stephan Gekle +4
A round disk with a harmonic disturbance impacts on a water surface and creates a non-axisymmetric cavity which collapses under the influence of hydrostatic pressure. We use disks…
Supersonic Air Flow due to Solid-Liquid Impact
Stephan Gekle, Ivo Peters, Jose Manuel Gordillo +2
A solid object impacting on liquid creates a liquid jet due to the collapse of the impact cavity. Using visualization experiments with smoke particles and multiscale simulations we…
Generation and Breakup of Worthington Jets After Cavity Collapse
Stephan Gekle, J. M. Gordillo
Helped by the careful analysis of their experimental data, Worthington (1897) described roughly the mechanism underlying the formation of high-speed jets ejected after the impact o…
Nucleation threshold and deactivation mechanisms of nanoscopic cavitation nuclei
Bram M. Borkent, Stephan Gekle, Andrea Prosperetti +1
The acoustic nucleation threshold for bubbles trapped in cavities has theoretically been predicted within the crevice theory by Atchley & Prosperetti [J. Acoust. Soc. Am. 86, 1065-…
Approach to Universality in Axisymmetric Bubble Pinch-Off
Stephan Gekle, Devaraj van der Meer, Jacco H. Snoeijer +1
The pinch-off of an axisymmetric air bubble surrounded by an inviscid fluid is compared in four physical realizations: (i) cavity collapse in the wake of an impacting disc, (ii) ga…
