Energy partition, scale by scale, in magnetic Archimedes Coriolis weak wave turbulence

Article dans Phys. Rev. E (2017)

Energy partition, scale by scale, in magnetic Archimedes Coriolis weak wave turbulence

A. Salhi, F. S. Baklouti, F. Godeferd, T. Lehner, and C. Cambon

Magnetic Archimedes Coriolis (MAC) waves are omnipresent in several geophysical and astrophysical flows such as the solar tachocline. In the present study, we use linear spectral theory (LST) and (...)

Alternative formulation to incorporate forcing terms in a lattice Boltzmann scheme with central moments

Article dans Phys. Rev. E (2017)

Alternative formulation to incorporate forcing terms in a lattice Boltzmann scheme with central moments

Alessandro De Rosis

Within the framework of the central-moment-based lattice Boltzmann method, we propose a strategy to account for external forces in two and three dimensions. Its numerical properties are evaluated (...)

Dissipation in unsteady turbulence

Wouter J.T. Bos, Robert Rubinstein

Recent experiments and simulations have shown that unsteady turbulent flows display a universal behavior at short and intermediate times, different from classical scaling relations. The origin of (...)

Buoyancy-driven bubbly flows : ordered and free rise at small and intermediate volume fraction

Article dans J. Fluid Mech. (2017)

Buoyancy-driven bubbly flows : ordered and free rise at small and intermediate volume fraction

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

Various expressions have been proposed previously for the rise velocity of gas bubbles in homogeneous steady bubbly flows, generally a monotonically decreasing function of the bubble volume (...)

An efficient 1D numerical model adapted to the study of transient convecto-diffusive heat and mass transfer in directional solidification

Article dans Int. J. Heat Mass Transf. (2017)

An efficient 1D numerical model adapted to the study of transient convecto-diffusive heat and mass transfer in directional solidification

VirgileTavernier, Séverine Millet, Daniel Henry, Valéry Bottona, Ghislain Boutet, Jean-Paul Garandet

We combine an effective diffusivity model with a numerical approach initially proposed by Meyer (1981) to simulate transient heat and mass transfer phenomena in a directionally solidifying Sn-Bi (...)

Central-moments–based lattice Boltzmann schemes with force-enriched equilibria

Article dans Europhys. Lett. (2017)

Central-moments–based lattice Boltzmann schemes with force-enriched equilibria

Alessandro De Rosis

This paper presents a numerical scheme to account for external forces in the central-moments–based lattice Boltzmann method. Instead of deriving additional forcing operators, here we propose to (...)

Direct numerical simulations of homogeneous isotropic turbulence in a dense gas

Article dans J. Phys. Conf. Series (2017)

Direct numerical simulations of homogeneous isotropic turbulence in a dense gas

A. Giauque, C. Corre and M. Menghetti

A study of turbulence in BZT dense gas flows is performed using DNS. It is shown that for a large but realistic intensity, the turbulence in dense gas flows behaves in a highly compressible (...)

Overview of and first observations from the TILDAE High-Altitude Balloon Mission

Bennett A. Maruca, Raffaele Marino, David Sundkvist, Niharika H. Godbole, Stephane Constantin, Vincenzo Carbone, and Herb Zimmerman

Though the presence of intermittent turbulence in the stratosphere has been well established, much remains unknown about it. In situ observations of this phenomenon, which have provided the (...)

Pressure dependence of the electrical transport in granular materials

Article dans Eur. Phys. J. E (2017)

Pressure dependence of the electrical transport in granular materials

M. Creyssels, C. Laroche, E. Falcon, B. Castaing

We report on systematic measurements of the electrical resistance of one- and three-dimensional (1D and 3D) metallic and oxidized granular materials under uni-axial compression. Whatever the (...)

Laminar-turbulent transition regimes in the conical Taylor-Couette flow system

Fatma Yahi, Ahcene Bouabdallah, Yasmina Hamnoune, Valéry Botton, Daniel Henry, Séverine Millet, François Rousset and Takahiro Adachi

The present work is intended to experimentally study the Taylor-Couette flow between coaxial cones. The inner cone is rotated and the outer cone is maintained fixed. Both cones have the same apex (...)
