Disentangling temperature and Reynolds number effects in quantum turbulence
Juan Ignacio Polanco, Philippe-E. Roche, Luminita Danaila +1
The interplay between viscous and frictional dissipation is key to understanding quantum turbulence dynamics in superfluid He. Based on a coarse-grained two-fluid description,…
A soft particle dynamics method based on shape degrees of freedom
Yohann Trivino, Vincent Richefeu, Farhang Radjai +2
In this paper, we present a 2D numerical model developed to simulate the dynamics of soft, deformable particles. To accommodate significant particle deformations, the particle surf…
Active grid turbulence anomalies through the lens of physics informed neural networks
Sofía Angriman, Sarah E. Smith, Patricio Clark di Leoni +3
Active grids operated with random protocols are a standard way to generate large Reynolds number turbulence in wind and water tunnels. But anomalies in the decay and third-order sc…
Fast and accurate evaluation of Biot-Savart integrals over spatial curves in periodic domains
Juan Ignacio Polanco
The Biot-Savart law is relevant in physical contexts including electromagnetism and fluid dynamics. In the latter case, when the rotation of a fluid is confined to a set of very th…
Space-time statistics of 2D soliton gas in shallow water studied by stereoscopic surface mapping
Thibault Leduque, Eric Barthélemy, Hervé Michallet +2
We describe laboratory experiments in a 2D wave tank that aim at building up and monitor 2D shallow water soliton gas. The water surface elevation is obtained over a large ($\sim 1…
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…
