Statistical Model for the Orientation of Nonspherical Particles Settling in Turbulence

Article in Phys. Rev. Lett. (2017)

Statistical Model for the Orientation of Nonspherical Particles Settling in Turbulence

K. Gustavsson, J. Jucha, A. Naso, E. Lévêque, A. Pumir, and B. Mehlig

The orientation of small anisotropic particles settling in a turbulent fluid determines some essential properties of the suspension. We show that the orientation distribution of small heavy (...)

Disproportionate entrance length in superfluid flows and the puzzle of counterflow instabilities

Article in Phys. Rev. Fluids (2017)

Disproportionate entrance length in superfluid flows and the puzzle of counterflow instabilities

J. Bertolaccini, E. Lévêque, and P.-E. Roche

Systematic simulations of the two-fluid model of superfluid helium (He-II) encompassing the Hall-Vinen-Bekharevich-Khalatnikov (HVBK) mutual coupling have been performed in two-dimensional pipe (...)

From flying wheel to square flow: Dynamics of a flow driven by acoustic forcing

Article in Phys. Rev. Fluids (2017)

From flying wheel to square flow: Dynamics of a flow driven by acoustic forcing

Tristan Cambonie, Brahim Moudjed, Valéry Botton, Daniel Henry, and Hamda Ben Hadid

Acoustic streaming designates the ability to drive quasisteady flows by acoustic propagation in dissipative fluids and results from an acoustohydrodynamics coupling. It is a noninvasive way of (...)

Small-scale anisotropy induced by spectral forcing and by rotation in non-helical and helical turbulence

Article in J. Turbul. (2017)

Small-scale anisotropy induced by spectral forcing and by rotation in non-helical and helical turbulence

Donato Vallefuoco, Aurore Naso, Fabien S. Godeferd

We study the effect of large-scale spectral forcing on the scale-dependent anisotropy of the velocity field in direct numerical simulations of homogeneous turbulence. ABC-type forcing and helical (...)

Effect of rotation on the stability of side-heated buoyant convection between infinite horizontal walls

Article in Phys. Rev. Fluids (2017)

Effect of rotation on the stability of side-heated buoyant convection between infinite horizontal walls

Abdessamed Medelfef, Daniel Henry, Ahcene Bouabdallah, Slim Kaddeche, and Redouane Boussaa

This paper deals with buoyant convection generated by a horizontal gradient of temperature in an infinite fluid layer, which is known as Hadley circulation, and studies the effects induced by (...)

Direct numerical simulation of axisymmetric turbulence

Article in Phys. Rev. Fluids (2017)

Direct numerical simulation of axisymmetric turbulence

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

The dynamics of decaying, strictly axisymmetric, incompressible turbulence is investigated using direct numerical simulations. It is found that the angular momentum is a robust invariant of the (...)

A New Strategy for Analysis and Visualization of Massively Parallel Computations of Turbulent and Transitional Flows

Article in Notes Num. Fluid Mech. (2018)

A New Strategy for Analysis and Visualization of Massively Parallel Computations of Turbulent and Transitional Flows

Anne Cadiou, Marc Buffat, Bastien Di Pierro, Lionel Le Penven, Christophe Pera

Massively parallel simulations generate increasing volumes of large data, whose exploitation requires large storage resources, efficient network and increasingly large post-processing facilities. (...)

Influence of source conditions and heat losses on the upwind back-layering flow in a longitudinally ventilated tunnel

Article in Int. J. Heat Mass Transf. (2018)

Influence of source conditions and heat losses on the upwind back-layering flow in a longitudinally ventilated tunnel

Pietro Salizzoni, Mathieu Creyssels, Lei Jiang, A. Mos, R. Mehaddi, O. Vauquelin

We study experimentally the dynamics of a back-layering flow developing below the ceiling of a longitudinally ventilated tunnel, and induced by the presence of a steady source of buoyancy at the (...)

Inverse cascades and resonant triads in rotating and stratified turbulence

Article in Phys. Fluids (2017)

Inverse cascades and resonant triads in rotating and stratified turbulence

D. Oks, P. D. Mininni, R. Marino, and A. Pouquet

Kraichnan’s seminal ideas on inverse cascades yielded new tools to study common phenomena in geophysical turbulent flows. In the atmosphere and the oceans, rotation and stratification result in a (...)

Dual constant-flux energy cascades to both large scales and small scales

Article in Phys. Fluids (2017)

Dual constant-flux energy cascades to both large scales and small scales

A. Pouquet, R. Marino, P. D. Mininni, and D. Rosenberg

In this paper, we present an overview of concepts and data concerning inverse cascades of excitation towards scales larger than the forcing scale in a variety of contexts, from two-dimensional (...)

Influence of noncondensable gases on thermodynamic control on-ground experiments using a substitute fluid

Article in J. Therm. Sci. Eng. Appl. (2018)

Influence of noncondensable gases on thermodynamic control on-ground experiments using a substitute fluid

Samuel Mer, Jean-Paul Thibault & Christophe Corre

A cryogenic propellant submitted to heat load during long duration space missions tends to vaporize to such an extent that the resulting pressure rise must be controlled to prevent storage (...)
