Spectral modelling of high Reynolds number unstably stratified homogeneous turbulence

Article in J. Fluid Mech. (2015)

Spectral modelling of high Reynolds number unstably stratified homogeneous turbulence

A. Burlot, B.-J. Gréa, F. S. Godeferd, C. Cambon & J. Griffond

We study unconfined homogeneous turbulence with a destabilizing background density gradient in the Boussinesq approximation. Starting from initial isotropic turbulence, the buoyancy force induces (...)

Structure and dynamics of rotating turbulence: a review of recent experimental and numerical results

Article in Appl. Mech. Rev. (2015)

Structure and dynamics of rotating turbulence: a review of recent experimental and numerical results

Fabien Godeferd & Frédéric Moisy

Rotating turbulence is a fundamental phenomenon appearing in several geophysical and industrial applications. Its study benefited from major advances in the recent years, but also raised new (...)

Numerical simulation and mathematical analysis of flow-wall interaction in the large deformation domain: application to the dynamics of the aneurysms

Article in J. Therm. Eng. (2015)

Numerical simulation and mathematical analysis of flow-wall interaction in the large deformation domain: application to the dynamics of the aneurysms

Mahmoud Hamadiche

A numerical method is derived to take account of full flow-wall interaction in la large deformation domain. To this end, a simplified Lagrangian and nonlinear model is derived to describe the (...)

Cyclone-anticyclone asymmetry and alignment statistics in homogeneous rotating turbulence

Article in Phys. Fluids (2015)

Cyclone-anticyclone asymmetry and alignment statistics in homogeneous rotating turbulence

Aurore Naso

The cyclone-anticyclone asymmetry occurring in rotating turbulence is investigated through the analysis of the alignment statistics between vorticity and the rotation vector. The advantage of (...)

Near-field acoustic streaming jet

Article in Phys. Rev. E (2015)

Near-field acoustic streaming jet

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

A numerical and experimental investigation of the acoustic streaming flow in the near field of a circular plane ultrasonic transducer in water is performed. The experimental domain is a (...)

Where large deep‐ocean waves break

Article in Geophys. Res. Lett. (2015)

Where large deep‐ocean waves break

Hans van Haren, Andrea Cimatoribus & Louis Gostiaux

Underwater topography like seamounts causes the breaking of large “internal waves” with associated turbulent mixing strongly affecting the redistribution of sediment. Here ocean turbulence is (...)

Experimental determination of the viscosity at very low shear rate for shear thinning fluids by electrocapillarity

Article in J. Non-Newtonian Fluid Mech. (2015)

Experimental determination of the viscosity at very low shear rate for shear thinning fluids by electrocapillarity

Mohamed Hatem Allouche, Valéry Botton, Daniel Henry, Séverine Millet, R. Usha, Hamda Ben Hadid

Non-Newtonian fluids can present a complex rheological behaviour involving shear-thinning, viscoelastic or thixotropic effects. We focus here on the characterization of generalized Newtonian (...)

Ground-induced lift enhancement in a tandem of symmetric flapping wings: Lattice Boltzmann-immersed boundary simulations

Article in Computers & Structures (2015)

Ground-induced lift enhancement in a tandem of symmetric flapping wings: Lattice Boltzmann-immersed boundary simulations

Alessandro De Rosis

The behavior of a tandem of symmetric flapping wings immersed in a quiescent viscous fluid is numerically dissected. The attention focuses on the effect on the flight performance of a solid (...)

The distribution of “time of flight” in three dimensional stationary chaotic advection

Article in Phys. Fluids (2015)

The distribution of “time of flight” in three dimensional stationary chaotic advection

Florence Raynal & Philippe Carrière

The distributions of “time of flight” (time spent by a single fluid particle between two crossings of the Poincaré section) are investigated for five different three dimensional stationary chaotic (...)
