Article dans Eur. J. Mech. B-Fluids (2019)
Lian Gan & Andrea Maffioli
This paper follows our previous study of forced non-solid-body rotating turbulence and summarises results on the eddy size and lifetime in the same flow. The experiment is conducted in a (...)

This study deals with the transition toward quasi-periodicity of buoyant convection generated by a horizontal temperature gradient in a three-dimensional parallelepipedic cavity with dimensions (...)

Geetanjali Chattopadhyay, Usha Ranganathan & Séverine Millet
A linear stability analysis of a pressure driven, incompressible, fully developed laminar Poiseuille flow of immiscible two-fluids of stratified viscosity and density in a horizontal channel (...)

Fraternale, F. Di Mare, R. Marino, B. Giles, T. E. Moore, C. T. Russell, R. B. Torbert, J. L. Burch & Y. V. Khotyaintsev
The description of the local turbulent energy transfer and the high-resolution ion distributions measured by the Magnetospheric Multiscale mission together provide a formidable tool to explore (...)

Frédéric Alizard & Damien Biau
A restricted nonlinear (RNL) model, obtained by partitioning the state variables into streamwise-averaged quantities and superimposed perturbations, is used in order to track the exact coherent (...)

Fawzi Fadla, Frédéric Alizard, Laurent Keirsbulck, Jean-Christophe Robinet, Jean-PhilippeLaval, Jean-Marc Foucaut, Camila Chovet & Marc Lippert
Dynamical behavior of the turbulent channel flow separation induced by a wall-mounted two-dimensional bump is studied, with an emphasis on unsteadiness characteristics of vortical motions (...)

A. Pouquet, D. Rosenberg, J.E. Stawarz & R. Marino
We briefly review helicity dynamics, inverse and bidirectional cascades in fluid and magnetohydrodynamic (MHD) turbulence, with an emphasis on the latter. The energy of a turbulent system, an (...)

Aurore Naso
The structure of homogeneous rotating turbulence at moderate Reynolds number is investigated by analyzing the instantaneous statistics of the scale-dependent velocity gradient tensor perceived by (...)

Ying Zhu, Claude Cambon, Fabien. Godeferd & Aziz Salhi
We propose a statistical model for homogeneous turbulence undergoing distortions, which improves and extends the MCS model by Mons, Cambon & Sagaut (2016). The spectral tensor of two-point (...)

Efficient numerical models are derived for problems of natural convection and material solidification in a horizontal differentially heated slender cavity. These 2D½ models are obtained by (...)
