The clustering morphology of freely rising deformable bubbles
Yoshiyuki Tagawa, Ivo Roghair, Vivek N. Prakash +4
We investigate the clustering morphology of a swarm of freely rising deformable bubbles. A three-dimensional Voronoï analysis enables us to quantitatively distinguish between two t…
Needle-free injection into skin and soft matter with highly focused microjets
Yoshiyuki Tagawa, Nikolai Oudalov, A. El Ghalbzouri +2
The development of needle-free drug injection systems is of great importance to global healthcare. However, in spite of its great potential and research history over many decades,…
Inside a kettle
S. Wildeman, H. Lhuissier, C. Sun +1
This fluid dynamics video images the different heat transport mechanisms at play when a liquid confined in a vertical Hele-Shaw cell is heated from below. The two-dimensional time…
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…
Sonoluminescence and sonochemiluminescence from a microreactor
David Fernandez Rivas, Muthupandian Ashokkumar, Thomas Leong +5
Micromachined pits on a substrate can be used to nucleate and stabilize microbubbles in a liquid exposed to an ultrasonic field. Under suitable conditions, the collapse of these bu…
