Predicting the dynamics of a gas pocket during breaking wave impacts using machine learning
Rodrigo Ezeta, Bulent Düz
We investigate the feasibility and accuracy of a machine learning model to predict the dynamics of a gas pocket that is formed when a breaking wave impacts on a solid wall. The pro…
Catastrophic phase inversion in high-Reynolds number turbulent Taylor--Couette flow
Dennis Bakhuis, Rodrigo Ezeta, Pim A. Bullee +4
Emulsions are omnipresent in the food industry, health care, and chemical synthesis. In this Letter the dynamics of meta-stable oil-water emulsions in highly turbulent ($10^{11}\le…
Double maxima of angular momentum transport in TC turbulence
Rodrigo Ezeta, Francesco Sacco, Dennis Bakhuis +5
We use experiments and direct numerical simulations to probe the phase-space of low-curvature Taylor--Couette (TC) flow in the vicinity of the ultimate regime. The cylinder radius…
Effect of axially varying sandpaper roughness on bubbly drag reduction in Taylor-Couette turbulence
Pim A. Bullee, Dennis Bakhuis, Rodrigo Ezeta +4
We experimentally investigate the influence of alternating rough and smooth walls on bubbly drag reduction (DR). We apply rough sandpaper bands of width between and…
Drag reduction in boiling Taylor-Couette turbulence
Rodrigo Ezeta, Dennis Bakhuis, Sander G. Huisman +2
We create a highly controlled lab environment-accessible to both global and local monitoring-to analyse turbulent boiling flows and in particular their shear stress in a statistica…
Statistics, plumes and azimuthally traveling waves in ultimate Taylor-Couette turbulent vortices
Andreas Froitzheim, Rodrigo Ezeta, Sander G. Huisman +4
In this paper, we experimentally study the influence of large-scale Taylor rolls on the small-scale statistics and the flow organization in fully turbulent Taylor-Couette flow {for…
Statistics of rigid fibers in strongly sheared turbulence
Dennis Bakhuis, Varghese Mathai, Ruben A. Verschoof +4
Practically all flows are turbulent in nature and contain some kind of irregularly-shaped particles, e.g. dirt, pollen, or life forms such as bacteria or insects. The effect of the…
Controlling secondary flow in Taylor-Couette turbulence through spanwise-varying roughness
Dennis Bakhuis, Rodrigo Ezeta, Pieter Berghout +7
Highly turbulent Taylor-Couette flow with spanwise-varying roughness is investigated experimentally and numerically (direct numerical simulations (DNS) with an immersed boundary me…
Turbulence strength in ultimate Taylor-Couette turbulence
Rodrigo Ezeta, Sander G. Huisman, Chao Sun +1
We provide experimental measurements for the effective scaling of the Taylor-Reynolds number within the bulk , based on local flow quantities as a functi…
