Air entrainment by turbulent plunging jets: effect of jet roughness revisited
Ivan Redor, Gregory Guyot, Martin Obligado +2
The amount of air entrained by vertical water jets impacting a large pool is revisited. To test available phenomenological models, new data on the jet deformation at impact and on…
Onset of Air Entrainment by a smooth plunging jet under atmospheric pressure
Alain Cartellier, Juan Lasheras
The onset of air entrainment by a smooth vertical liquid jet impacting a pool of the same liquid has been experimentally determined. The ranges of parameters covered complement tho…
Buoyancy driven bubbly flows: role of meso-scale structures on the relative motion between phases in bubble columns operated in the heterogeneous regime
Y. Mezui, M. Obligado, A. Cartellier
The hydrodynamics of bubble columns in the heterogeneous regime is investigated from experiments with bubbles at large particle Reynolds numbers and without coalescence. The void f…
Buoyancy driven bubbly flows: scaling of velocities in bubble columns operated in the heterogeneous regime
Y. Mezui, M. Obligado, Alain Cartellier
The hydrodynamics of bubble columns in the heterogeneous regime is revisited. Focusing on air-water systems at large aspect ratio, we show from dimensional analysis that buoyancy e…
A new, optimized Doppler optical probe for phase detection, bubble velocity and size measurements: investigation of a bubble column operated in the heterogeneous regime
Anthony Lefebvre, Yann Mezui, Martin Obligado +2
A new measuring technique dedicated to bubble velocity and size measurements in complex bubbly flows such as those occurring in bubble columns is proposed. This sensor combines the…
The effect of and Rouse numbers on the settling of inertial particles in homogeneous isotropic turbulence
Daniel Odens Mora, Martin Obligado, Alberto Aliseda +1
We present an experimental study on the settling velocity of dense sub-Kolmogorov particles in active-grid-generated turbulence in a wind tunnel. Using phase Doppler interferometry…
