Extreme fluctuations of the relative velocities between droplets in turbulent airflow
Ewe-Wei Saw, Gregory P. Bewley, Eberhard Bodenschatz +2
We compare experiments and direct numerical simulations to evaluate the accuracy of the Stokes-drag model, which is used widely in studies of inertial particles in turbulence. We f…
On the Relaxation of Turbulence at High Reynolds Numbers
Michael Sinhuber, Eberhard Bodenschatz, Gregory P. Bewley
Turbulent motions in a fluid relax at a certain rate once stirring has stopped. The role of the most basic parameter in fluid mechanics, the Reynolds number, in setting the relaxat…
Time-symmetry breaking in turbulence
Jennifer Jucha, Haitao Xu, Alain Pumir +1
In three-dimensional turbulent flows, the flux of energy from large to small scales breaks time symmetry. We show here that this irreversibility can be quantified by following the…
Logarithmic Spatial Variations and Universal Power Spectra of Temperature Fluctuations in Turbulent Rayleigh-Bénard Convection
Xiaozhou He, Dennis P. M. van Gils, Eberhard Bodenschatz +1
We report measurements of the temperature variance and frequency power spectrum ( is the distance from the sample bottom and the radial coordinate) in…
Logarithmic temperature profiles of turbulent Rayleigh-Bénard convection in the classical and ultimate state for a Prandtl number of 0.8
Guenter Ahlers, Eberhard Bodenschatz, Xiaozhou He
We report on experimental determinations of the temperature field in the interior (bulk) of turbulent Rayleigh-Benard convection for a cylindrical sample with aspect ratio (diamete…
Observation of the sling effect
Gregory P. Bewley, Ewe Wei Saw, Eberhard Bodenschatz
When cloud particles are small enough, they move with the turbulent air in the cloud. On the other hand, as particles become larger their inertia affects their motions, and they mo…
