On the triggering of the Ultimate Regime of convection
Philippe-E. Roche, Frédéric Gauthier, Robert Kaiser +1
Rayleigh-Bénard cells are one of the simplest systems to explore the laws of natural convection in the highly turbulent limit. However, at very high Rayleigh numbers (Ra > 1E12) an…
Turbulent velocity spectra in superfluid flows
J. Salort, C. Baudet, B. Castaing +12
We present velocity spectra measured in three cryogenic liquid 4He steady flows: grid and wake flows in a pressurized wind tunnel capable of achieving mean velocities up to 5 m/s a…
Mesoscale Equipartition of kinetic energy in Quantum Turbulence
Julien Salort, Philippe-E. Roche, Emmanuel Lévêque
The turbulence of superfluid helium is investigated numerically at finite temperature. Direct numerical simulations are performed with a "truncated HVBK" model, which combines the…
