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,…
Wall forces on a sphere in a rotating liquid-filled cylinder
Yoshiyuki Tagawa, Jarich van der Molen, Leen van Wijngaarden +1
We experimentally study the behavior of a particle slightly denser than the surrounding liquid in solid body rotating flow. Earlier work revealed that a heavy particle has an unsta…
Microdroplet impact at very high velocity
Claas Willem Visser, Yoshiyuki Tagawa, Chao Sun +1
Water microdroplet impact at velocities up to 100 m/s for droplet diameters from 12 to 100 um is studied. This parameter range covers the transition from capillary-limited to visco…
How gravity and size affect the acceleration statistics of bubbles in turbulence
Vivek N. Prakash, Yoshiyuki Tagawa, Enrico Calzavarini +4
We report results from the first systematic Lagrangian experimental investigation in the regime of very light (air bubbles in water) and large particles (D/η >> 1) in turbulence. U…
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…
