Nonlocal energy transfer mechanism in three-dimensional quantum turbulence
Elliot Bes, Guillaume Balarac, Juan Ignacio Polanco
We investigate the kinetic energy cascade in zero-temperature quantum turbulence. Using simple theoretical arguments and unprecedented numerical simulations, we unveil an universal…

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,…

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…
