### Model for classical and ultimate regimes of radiatively driven turbulent convection

Mathieu Creyssels

In a standard Rayleigh–Bénard experiment, a layer of fluid is confined between two horizontal plates and the convection regime is controlled by the temperature difference between the hot lower (...)

### Linearly forced isotropic turbulence at low Reynolds numbers

Wouter Bos, Faouzi Laadhari & Wesley Agoua

The forcing strength needed to sustain a flow using linear forcing is investigated. A critical Reynolds number $R_c$ is determined, based on the longest wavelength allowed by the system, the (...)

### The role of velocity derivative skewness in understanding non-equilibrium turbulence

Feng Liu, Le Fang & Liang Shao

The turbulence governed by the Navier–Stokes equation is paramount in many physical processes. However, it has been considered as a challenging problem due to its inherent nonlinearity, (...)

### Turbulence modelling analysis in a corner separation flow

Jean-François Monier, Feng Gao, Jérôme Boudet & Liang Shao

This paper studies RANS turbulence modelling for a linear compressor cascade corner separation flow, using large-eddy simulation results as reference. The Boussinesq and the quadratic (...)

### New strategy of solid/fluid coupling during numerical simulation of thermo-mechanical processes

Yassine Saadlaoui, Alexandre Delache, Éric Feulvarch, Jean-Baptiste Leblond & Jean-Michel Bergheau

In this study, numerical methods are developed to simulate thermomechanical processes, taking into account both the fluid flows in the molten pool and the deformations of the solid parts. The (...)

### Generation of Atmospheric Turbulence with Unprecedentedly Large Reynolds Number in a Wind Tunnel

Lars Neuhaus, Michael Hölling, Wouter Bos & Joachim Peinke

Generating laboratory flows resembling atmospheric turbulence is of prime importance to study the effect of wind fluctuations on objects such as buildings, vehicles, or wind turbines. A novel (...)

### Calculation of a key function in the asymptotic description of moving contact lines

Julian Scott

An important element of the asymptotic description of flows having a moving liquid/gas interface which intersects a solid boundary is a function denoted $Q_i(\alpha)$ by Hocking and Rivers (The (...)

### Production and dissipation of kinetic energy in grid turbulence

Wouter Bos

In grid turbulence, not so far behind the grid, an average flow can be observed with a close to sinusoidal velocity profile, corresponding to the wakes behind the grid bars. The kinetic energy of (...)

### A phenomenological and multiscale modeling of arterial growth and remodeling under endofibrosis

Jérôme Jansen, Xavier Escriva, Fabien Godeferd & Patrick Feugier

High level endurance sports, like biking, may lead to a vascular pathology called endofibrosis. Its symptoms are an arterial wall thickening and a reduction of the artery lumen calibre. Cyclists (...)

### Signature and energetics of internal gravity waves in stratified turbulence

Andrea Maffioli, Alexandre Delache & Fabien Godeferd

Internal gravity waves propagating within homogeneous stratified turbulence are the subject of the present study. A spatiotemporal analysis is carried out on the results of direct numerical (...)
