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

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 (...)

Scaling laws for mixing and dissipation in unforced rotating stratified turbulence

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 (...)

Improved Vortex Method for Large-eddy Simulation Inflow Generation

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 (...)

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

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 (...)

The effective diffusivity of ordered and freely evolving bubbly suspensions

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 (...)

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

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 (...)

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

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 (...)

Nonlinear travelling waves in rotating Hagen-Poiseuille flow

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 (...)

Cascades of energy and helicity in axisymmetric turbulence

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 (...)

Settling and collision between small ice crystals in turbulent flows

Article in Phys. Rev. Fluids (2018)

Settling and collision between small ice crystals in turbulent flows

Jennifer Jucha, Aurore Naso, Emmanuel Lévêque, and Alain Pumir

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 (...)
