Local and global properties of energy transfer in models of plasma turbulence

Article dans J. Plasma Phys. (2021)

Local and global properties of energy transfer in models of plasma turbulence

Christian L. Vásconez, D. Perrone, R. Marino, D. Laveder, F. Valentini, S. Servidio, P. Mininni & L. Sorriso-Valvo

The nature of the turbulent energy transfer rate is studied using direct numerical simulations of weakly collisional space plasmas. This is done comparing results obtained from hybrid (...)

Correlation between Buoyancy Flux, Dissipation and Potential Vorticity in Rotating Stratified Turbulence

Duane Rosenberg, Annick Pouquet & Raffaele Marino

We study in this paper the correlation between the buoyancy flux, the efficiency of energy dissipation and the linear and nonlinear components of potential vorticity, PV, a point-wise invariant (...)

Mixing and unmixing induced by active camphor particles

Article dans Phys. Rev. Fluids (2021)

Mixing and unmixing induced by active camphor particles

Clément Gouiller, Florence Raynal, Laurent Maquet, Mickaël Bourgoin, Cécile Cottin-Bizonne, Romain Volk & Christophe Ybert

Small colloidal floaters are poured at the air-water interface of a tank stirred by many camphor swimmers. The system rapidly reaches a statistically stationary state resulting in the competition (...)
