Transient growth in Poiseuille-Rayleigh-Bénard flows of binary fluids with Soret effect

Article in Appl. Math. Mech. (2016)

Transient growth in Poiseuille-Rayleigh-Bénard flows of binary fluids with Soret effect

Jun Hu, Daniel Henry, Hamda Ben Hadid, Xie-Yuan Yin

The transient growth due to non-normality is investigated for the Poiseuille-Rayleigh-Bénard problem of binary fluids with the Soret effect. For negative separation factors such as ψ = −0.1, it is (...)

Central-moment lattice Boltzmann schemes with fixed and moving immersed boundaries

Article in Comput. Math. App. (2016)

Central-moment lattice Boltzmann schemes with fixed and moving immersed boundaries

Alessandro De Rosis & Emmanuel Lévêque

Lattice Boltzmann (LB) schemes based on the relaxation of central moments have recently proved valuable in simulating flows with an improved stability with respect to the original (...)

Finite-size particles in turbulent channel flow: quadrant analysis and acceleration statistics

Article in J. Turbul. (2016)

Finite-size particles in turbulent channel flow: quadrant analysis and acceleration statistics

Wenchao Yu, Ivana Vinkovic & Marc Buffat

The interaction between finite-size particles and turbulent channel flow in the absence of gravity is studied by direct numerical simulations (DNS). The study is motivated by DNS observations of (...)

 Relation of the fourth-order statistical invariants of velocity gradient tensor in isotropic turbulence

Article in Phys. Rev. E (2016)

Relation of the fourth-order statistical invariants of velocity gradient tensor in isotropic turbulence

Le Fang, Y.J. Zhang, J. Fang, Ying Zhu

We show by direct numerical simulations (DNSs) that in different types of isotropic turbulence, the fourth-order statistical invariants have approximately a linear relation, which can be (...)

Supercritical dead water: effect of nonlinearity and comparison with observations

Article in J. Fluid Mech. (2016)

Supercritical dead water: effect of nonlinearity and comparison with observations

John Grue, Daniel Bourgault, Peter S. Galbraith

Supercritical ship internal wave wakes with $Fr=U/c_0\sim4–12$ (where $U$ is the ship speed and $c_0$ is the linear internal long-wave speed) are calculated by a strongly nonlinear two-layer model (...)

Instability of flow around a rotating, semi-infinite cylinder

Article in Phys. Rev. Fluids (2016)

Instability of flow around a rotating, semi-infinite cylinder

S. Derebail Muralidhar, Benoît Pier & Julian Scott

Stability of flow around a rotating, semi-infinite cylinder placed in an axial stream is investigated. Assuming large Reynolds number, the basic flow is computed numerically as described by (...)

Waves and vortices in the inverse cascade regime of stratified turbulence with or without rotation

Article in J. Fluid Mech. (2016)

Waves and vortices in the inverse cascade regime of stratified turbulence with or without rotation

Corentin Herbert, Raffaele Marino, Duane Rosenberg & Annick Pouquet

We study the partition of energy between waves and vortices in stratified turbulence, with or without rotation, for a variety of parameters, focusing on the behaviour of the waves and vortices in (...)

Le point sur les marées d'équinoxes dans l'estuaire du Saint-Laurent

Article in Le naturaliste Canadien (2016)

Le point sur les marées d’équinoxes dans l’estuaire du Saint-Laurent

Daniel Bourgault, Cédric Chavanne, Dany Dumont, Émilie Morin, Peter S. Galbraith & Louis Gostiaux

According to a study published in Le Naturaliste canadien, tides in the St. Lawrence Estuary would not be any greater at the equinoxes than they are at any other moment of the year. According to (...)

Optimal design of a thermodynamic vent system for cryogenic propellant storage

Article in Cryogenics (2016)

Optimal design of a thermodynamic vent system for cryogenic propellant storage

Samuel Mer, David Fernandez, Jean-Paul Thibault & Christophe Corre

Future operations in space exploration require to store cryogenic liquids for long duration. Residual heat loads, due to heat conduction in the launcher structure or solar radiation, induce (...)

Small scale dynamics of isotropic viscoelastic turbulence

Article in Phys. Rev. Fluids (2016)

Small scale dynamics of isotropic viscoelastic turbulence

Min Quan Nguyen, Alexandre Delache, Serge Simoëns, Wouter J. T. Bos & Mamoud El Hajem

The comparison of the results of direct numerical simulations of isotropic turbulence of Newtonian and viscoelastic fluid provides evidence that viscoelasticity modifies qualitatively the (...)
