### Global stability analysis of flow through a fusiform aneurysm : steady flows

Shyam Sunder Gopalakrishnan, Benoît Pier & Arie Biesheuvel

The global linear stability of steady axisymmetric flow through a model fusiform aneurysm is studied numerically. The aneurysm is modelled as a Gaussian-shaped inflation on a vessel of circular (...)

### Strain and Stratification Effects on the Rapid Acceleration of a Turbulent Mixing Zone

Benoît-Joseph Gréa, Jérôme Griffond & Fabien Godeferd

We consider the problem of a turbulent mixing zone (TMZ), initially submitted to coupled effects of axisymmetric strain and stratification, then subsequently accelerated. The TMZ grows in the (...)

### Chaotic mixing in effective compressible flows

R. Volk, C. MaugerM. Bourgoin, C. Cottin-Bizonne, C. Ybert & F. Raynal

We study numerically joint mixing of salt and colloids by chaotic advection and how salt inhomogeneities accelerate or delay colloid mixing by inducing a velocity drift V$_\rm dp$ between (...)

### The effect of toroidicity on reversed field pinch dynamics

Jorge A. Morales, Wouter J. T. Bos, Kai Schneider & David C. Montgomery

The influence of the curvature of the imposed magnetic field on reversed field pinch dynamics is investigated by comparing the flow of a magnetofluid in a torus with aspect ratio 1.83, with the (...)

### Bifurcation analysis of steady natural convection in a tilted cubical cavity with adiabatic sidewalls

J. F. Torres, D. Henry, A. Komiya & S. Maruyama

Natural convection in an inclined cubical cavity heated from two opposite walls maintained at different temperatures and with adiabatic sidewalls is investigated numerically. The cavity is (...)

### Scaling and dimensional analysis of acoustic streaming jets

B. Moudjed, V. Botton, D. Henry, H. Ben Hadid & J.-P. Garandet

This paper focuses on acoustic streaming free jets. This is to say that progressive acoustic waves are used to generate a steady flow far from any wall. The derivation of the governing equations (...)

### Comparison of Ellison and Thorpe scales from Eulerian ocean temperature observations

Andrea A. Cimatoribus, Hans van Haren & Louis Gostiaux

Ocean turbulence dissipation rate is estimated either by means of microstructure shear measurements, or by adiabatically reordering vertical profiles of density. The latter technique leads to the (...)

### Recent understanding on the subgrid-scale modeling of large-eddy simulation in physical space

Le Fang, Liang Shao & Jean-Pierre Bertoglio

In the last 50 years, the methodology of large-eddy simulation (LES) has been greatly developed, while lots of different subgridscale (SGS) models have appeared. However, the understanding of the (...)

### Dynamics of pulsatile flow through model abdominal aortic aneurysms

Shyam Sunder Gopalakrishnan, Benoît Pier & Arie Biesheuvel

To contribute to the understanding of flow phenomena in abdominal aortic aneurysms, numerical computations of pulsatile flows through aneurysm models and a stability analysis of these flows were (...)

### Oscillating acoustic streaming jet

Brahim Moudjed, Valéry Botton, Daniel Henry, Séverine Millet, Jean-Paul Garandet & Hamda Ben-Hadid

The present paper provides the first experimental investigation of an oscillating acoustic streaming jet. The observations are performed in the far field of a 2 MHz circular plane ultrasound (...)
