Energy spectra in turbulent bubbly flows
Vivek N. Prakash, Julian Martinez Mercado, Leen van Wijngaarden +4
We conduct experiments in a turbulent bubbly flow to study the nature of the transition between the classical 5/3 energy spectrum scaling for a single-phase turbulent flow and t…
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…
Lagrangian statistics of light particles in turbulence
Julian Martinez Mercado, Vivek N. Prakash, Yoshiyuki Tagawa +2
We study the Lagrangian velocity and acceleration statistics of light particles (micro-bubbles in water) in homogeneous isotropic turbulence. Micro-bubbles with a diameter of 340 m…
Three-dimensional Lagrangian Voronoi analysis for clustering of particles and bubbles in turbulence
Yoshiyuki Tagawa, Julian Martinez Mercado, Vivek N. Prakash +3
Three-dimensional Voronoi analysis is used to quantify the clustering of inertial particles in homogeneous isotropic turbulence using data from numerics and experiments. We study t…
On bubble clustering and energy spectra in pseudo-turbulence
J. Martinez, D. Chehata, D. P. M. van Gils +2
3D-Particle Tracking (3D-PTV) and Phase Sensitive Constant Temperature Anemometry in pseudo-turbulence--i.e., flow solely driven by rising bubbles-- were performed to investigate b…
