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…
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…
Applying Laser Doppler Anemometry inside a Taylor-Couette geometry - Using a ray-tracer to correct for curvature effects
Sander G. Huisman, Dennis P. M. van Gils, Chao Sun
In the present work it will be shown how the curvature of the outer cylinder affects Laser Doppler anemometry measurements inside a Taylor-Couette apparatus. The measurement positi…
