Inverse cascades and resonant triads in rotating and stratified turbulence

Article dans 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 dans 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 (...)

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

Article dans 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 dans 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 (...)

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

Article dans 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 (...)

Statistical Model for the Orientation of Nonspherical Particles Settling in Turbulence

Article dans 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 dans 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 (...)
