Data-driven impeller model for efficient large eddy simulations of metastable von Kármán flows
Quentin Malé, Quentin Malé, Lucas Amoudruz +6
The von Kármán turbulent swirling flow exhibits intriguing large-scale metastable dynamics, including low-frequency state switching. The study of state switching demands long-durat…
Non-Gaussian statistics of concentration fluctuations in free liquid diffusion
Marco Bussoletti, Mirko Gallo, Amir Jafari +1
We show that the three-point skewness of concentration fluctuations is non-vanishing in free liquid diffusion, even in the limit of vanishingly small mean concentration gradients.…
Emergence of long-range non-equilibrium correlations in free liquid diffusion
Marco Bussoletti, Mirko Gallo, Amir Jafari +1
It is experimentally well-established that non-equilibrium long-range correlations of concentration fluctuations appear in free diffusion of a solute in a solvent, but it remains u…
Weak-Strong Uniqueness and Extreme Wall Events at High Reynolds Number
Gregory L. Eyink, Hao Quan
Singular or weak solutions of the incompressible Euler equations have been hypothesized to account for anomalous dissipation at very high Reynolds numbers and, in particular, to ex…
Whither the Zeroth Law of Turbulence?
Kartik P. Iyer, Theodore D. Drivas, Gregory L. Eyink +1
Experimental and numerical studies of incompressible turbulence suggest that the mean dissipation rate of kinetic energy remains constant as the Reynolds number tends to infinity (…
Weak-Strong Uniqueness and the d'Alembert Paradox
Hao Quan, Gregory L. Eyink
We prove conditional weak-strong uniqueness of the potential Euler solution for external flow around a smooth body in three space dimensions, within the class of viscosity weak sol…
