Article in J. Fluid Mech. (2018)

### Space–time dynamics of optimal wavepackets for streaks in a channel entrance flow

Frédéric Alizard, Anne Cadiou, Lionel Le Penven, Bastien Di Pierro & Marc Buffat

The laminar–turbulent transition of a plane channel entrance flow is revisited using global linear optimization analyses and direct numerical simulations. The investigated case corresponds to (...)

Article in J. Fluid Mech. (2018)

### Scaling laws for mixing and dissipation in unforced rotating stratified turbulence

Annick Pouquet, Duane Rosenberg, Raffaele Marino and Corentin Herbert

We present a model for the scaling of mixing in weakly rotating stratified flows characterized by their Rossby, Froude and Reynolds numbers , $Ro$, $Fr$, $Re$. This model is based on (...)

Article in Comput. Fluids (2018)

### Improved Vortex Method for Large-eddy Simulation Inflow Generation

BaolinXie, Feng Gao, Jérôme Boudet, Liang Shao & Lipeng Lu

The generation of turbulent inflow conditions in large-eddy simulation (LES) is a key ingredient for general applications of LES in both academic turbulent flows and industrial designs with (...)

Article in J. Comput. Phys. (2018)

### Simulations of viscous and compressible gas–gas flows using high-order finite difference schemes

Marion Capuano, Christophe Bogey & Peter Spelt

A computational method for the simulation of viscous and compressible gas–gas flows is presented. It consists in solving the Navier–Stokes equations associated with a convection equation governing (...)

Article in J. Fluid Mech. (2018)

### The effective diffusivity of ordered and freely evolving bubbly suspensions

Aurore Loisy, Aurore Naso & Peter D. M. Spelt

We investigate the dispersion of a passive scalar such as the concentration of a chemical species, or temperature, in homogeneous bubbly suspensions, by determining an effective diffusivity (...)

Article in Phys. Rev. E (2018)

### Self-similar regimes of turbulence in weakly coupled plasmas under compression

Giovanni Viciconte, Benoît-Joseph Gréa, & Fabien S. Godeferd

Plasmas under strong compression, as existing in inertial confinement fusion capsules, experience a tremendous growth of their viscosity coefficient due to the temperature increase. It is known (...)

Article in Solar Physics (2018)

### On the Statistical Properties of Turbulent Energy Transfer Rate in the Inner Heliosphere

Luca Sorriso-Valvo, Francesco Carbone, Silvia Perri, Antonella Greco, Raffaele Marino & Roberto Bruno

The transfer of energy from large to small scales in solar wind turbulence is an important ingredient of the long-standing question of the mechanism of the interplanetary plasma heating. Previous (...)

Article in Fluid Dyn. Res. (2018)

### Nonlinear travelling waves in rotating Hagen-Poiseuille flow

Benoît Pier & Rama Govindarajan

The dynamics of viscous flow through a rotating pipe is considered. Small-amplitude stability characteristics are obtained by linearizing the Navier—Stokes equations around the base flow and (...)

Article in Phys. Rev. Fluids (2018)

### Cascades of energy and helicity in axisymmetric turbulence

Bo Qu, Aurore Naso, & Wouter J. T. Bos

A spectral analysis of strictly axisymmetric turbulence is performed. Both freely decaying and statistically steady flows are considered. In helical flows we identify a dual cascade, where energy (...)

Ice crystals are present in a variety of clouds, at sufficiently low temperature. We consider here mixed-phase clouds which, at temperature ≳−20$^\circ$C, contain ice crystals, shaped approximately (...)
