A dynamic regularized gradient model of the subgrid-scale stress tensor for large-eddy simulation

Article in Phys. Fluids (2016)

A dynamic regularized gradient model of the subgrid-scale stress tensor for large-eddy simulation

Antoine Vollant, Guillaume Balarac & Christophe Corre

Large-eddy simulation (LES) solves only the large scales part of turbulent flows by using a scales separation based on a filtering operation. The solution of the filtered Navier-Stokes equations (...)

Shear improved Smagorinsky model for large eddy simulation of flow in a stirred tank with a Rushton disk turbine

Article in Chem. Eng. Res. Des. (2016)

Shear improved Smagorinsky model for large eddy simulation of flow in a stirred tank with a Rushton disk turbine

Satish Malik, Emmanuel Lévêque, Mounir Bouaif, Lionel Gamet, Églantine Flottes, Serge Simoens & Mahmoud El Hajem

Large eddy simulation (LES) is a very attractive method for simulations of reactive flows for a wide range of Reynolds number. In this approach, the effects observed at the large scales (for (...)

Insights from a 3-D temperature sensors mooring on stratified ocean turbulence

Article in Geophys. Res. Lett. (2016)

Insights from a 3-D temperature sensors mooring on stratified ocean turbulence

Hans van HareAndrea A. Cimatoribus, Frédéric Cyr & Louis Gostiaux

A unique small‐scale 3‐D mooring array has been designed consisting of five parallel lines, 100 m long and 4 m apart, and holding up to 550 high‐resolution temperature sensors. It is built for (...)

Convective mixing by internal waves in the Puerto Rico Trench

Article in J. Mar. Res. (2016)

Convective mixing by internal waves in the Puerto Rico Trench

Hans van Haren & Louis Gostiaux

A 2.4 km long deep-sea mooring was deployed for 14 months in the Puerto Rico Trench, the deepest part of the Atlantic Ocean. Below its top buoyancy package, the mooring line held a 200 m long (...)

Flow around a rotating semi-infinite cylinder in an axial stream

Article in Proc. R. Soc. A-Math. Phys. Eng. Sci (2016)

Flow around a rotating semi-infinite cylinder in an axial stream

S. Derebail Muralidhar, Benoît Pier, Julian Scott & Rama Govindarajan

This paper concerns steady, high-Reynolds-number flow around a semi-infinite, rotating cylinder placed in an axial stream and uses boundary-layer type of equations which apply even when the (...)

Dynamics and structure of unstably stratified homogeneous turbulence

Article in J. Turbul. (2016)

Dynamics and structure of unstably stratified homogeneous turbulence

Benoît-Joseph Gréa, Alan Burlot, Fabien S. Godeferd, Jérôme Griffond, Olivier Soulard, Claude Cambon

We characterise the properties of unstably stratified homogeneous turbulence by means of high-resolution direct numerical simulations and a two-point statistical spectral model based on a (...)

Spectral modelling for passive scalar dynamics in homogeneous anisotropic turbulence

Article in J. Fluid Mech. (2016)

Spectral modelling for passive scalar dynamics in homogeneous anisotropic turbulence

Antoine Briard, Thomas Gomez & Claude Cambon

The present work aims at developing a spectral model for a passive scalar field and its associated scalar flux in homogeneous anisotropic turbulence. This is achieved using the paradigm of (...)

Diffusiophoresis at the macroscale

Cyril Mauger, Romain Volk, Nathanaël Machicoane, Michaël Bourgoin, Cécile Cottin-Bizonne, Christophe Ybert & Florence Raynal

Diffusiophoresis, a ubiquitous phenomenon that induces particle transport whenever solute concentration gradients are present, was recently observed in the context of microsystems and shown to (...)
