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…
Lagrangian single particle turbulent statistics through the Hilbert-Huang Transform
Yongxiang Huang, Luca Biferale, Enrico Calzavarini +2
The Hilbert-Huang transform is applied to analyze single particle Lagrangian velocity data from numerical simulations of hydrodynamic turbulence. The velocity trajectory is describ…
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…
Maximal air bubble entrainment at liquid drop impact
Wilco Bouwhuis, Roeland C. A. van der Veen, Tuan Tran +7
At impact of a liquid drop on a solid surface an air bubble can be entrapped. Here we show that two competing effects minimize the (relative) size of this entrained air bubble: For…
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…
