Scaling laws and local enhancements of buoyancy flux in stratified turbulent flows
Gyeongseob Song, Fabio Feraco, Raffaele Marino +6
In the presence of stratification, turbulent flows exhibit intermittency not only at small scales but also at large scales, comparable to the mean flow, as observed in the atmosphe…
Relation between the moments of longitudinal velocity derivatives and of dissipation in turbulence
Ping-Fan Yang, Haitao Xu, Alain Pumir
In homogeneous and isotropic turbulence, measurements of the longitudinal velocity derivative, , make it possible to estimate a surrogate of the rate of energy diss…
The contribution of dilatational motion to energy flux in homogeneous compressible turbulence
Chensheng Luo, Le Fang, Jian Fang +3
We analyze the energy flux in compressible turbulence by generalizing the exact decomposition recently proposed by Johnson (Phys. Rev. Lett., vol. 124, 2020. 104501) to study incom…
Universality of extreme events in turbulent flows
Dhawal Buaria, Alain Pumir
The universality of small scales, a cornerstone of turbulence, has been nominally confirmed for low-order mean-field statistics, such as the energy spectrum. However, small scales…
Multi-Particle Dispersion in Rotating-Stratified Turbulent Flows
Sebastian Gallon, Fabio Feraco, Raffaele Marino +1
The transport of matter by turbulent flows plays an important role, in particular in a geophysical context. Here, we study the relative movement of groups of two (pairs) and four (…
Lagrangian irreversibility and energy exchanges in rotating-stratified turbulent flows
Sebastian Gallon, Alessandro Sozza, Fabio Feraco +2
Turbulence in stratified and rotating turbulent flows is characterized by an interplay between waves and eddies, resulting in continuous exchanges between potential and kinetic ene…
Vertical drafts and mixing in stratified turbulence: sharp transition with Froude number
F. Feraco, R. Marino, A. Pumir +4
We investigate the large-scale intermittency of vertical velocity and temperature, and the mixing properties of stably stratified turbulent flows using both Lagrangian and Eulerian…
