Taming Acoustic Cavitation
David Fernandez Rivas, Bram Verhaagen, Oscar R. Enriquez +4
In this fluid dynamics video we show acoustic cavitation occurring from pits etched on a silicon surface. By immersing the surface in a liquid, gas pockets are entrapped in the pit…
Efficient Sonochemistry through Microbubbles Generated with Micromachined Surfaces
David Fernandez Rivas, Andrea Prosperetti, Aaldert G. Zijlstra +2
Sonochemical reactors are used in water treatment, the synthesis of fine chemicals, pharmaceutics and others. The low efficiency of sonoreactors have prevented its massive usage at…
Oscillations of a gas pocket on a liquid-covered solid surface
Hanneke Gelderblom, Aaldert G. Zijlstra, Leen van Wijngaarden +1
The dynamic response of a gas bubble entrapped in a cavity on the surface of a submerged solid subject to an acoustic field is investigated in the linear approximation. We derive s…
Highly focused supersonic microjets: numerical simulations
Ivo R. Peters, Yoshiyuki Tagawa, Nikolai Oudalov +4
By focusing a laser pulse inside a capillary partially filled with liquid, a vapour bubble is created which emits a pressure wave. This pressure wave travels through the liquid and…
