Article dans Computers & Fluids (2020)
J. Chai, Le Fang & Jean-Pierre Bertoglio
The two-dimensional hexagonal Fourier transform is introduced to reduce the background anisotropy in the numerical calculations with periodic conditions. Comparing to traditional Fourier (...)
Article dans J. of Physics : Conf. Series (2020)
Anne Cadiou, Marc Buffat, Christophe Pera, Bastien Di Pierro, Frédéric Alizard & Lionel Le Penven
The increase of computational resources with the generalization of massively parallel supercomputers benefits to various fields of physics among which turbulence and fluid mechanics, making it (...)
Article dans J. Non-Newtonian Fluid Mech. (2020)
Haining Luo, Alexandre Delache & Serge Simoëns
In this paper, we present result from a direct numerical simulation (DNS) of turbulent flow in a converging T-junction for both Newtonian (water) and non-Newtonian inelastic fluid (dilute Xanthan (...)
Article dans Phys. Rev. X (2020)
Mickaël Bourgoin, Ronan Kervil, Cécile Cottin-Bizonne, Florence Raynal, Romain Volk & Christophe Ybert
Active matter, composed of self-propelled entities, forms a wide class of out-of-equilibrium systems that display striking collective behaviors, among which, the so-called active turbulence where (...)
Article dans Phys. Rev. Fluids (2020)
Zecong Qin, Hugues Faller, Bérengère Dubrulle, Aurore Naso & Wouter Bos
Strictly axisymmetric turbulence, i.e., turbulence governed by the Navier-Stokes equations modified such that the flow is invariant in the azimuthal direction, is a system intermediate between (...)
Article dans Phys. Rev. Fluids (2020)
Dhawal Buaria, Alain Pumir, Fabio Feraco, Raffaele Marino, Annick Pouquet, Duane Rosenberg & Leonardo Primavera
Geophysical fluid flows are predominantly turbulent and often strongly affected by the Earth’s rotation, as well as by stable density stratification. Using direct numerical simulations of forced (...)
Article dans J. Fluid. Mech. (2020)
Thibault Lestang, Freddy Bouchet & Emmanuel Lévêque
This study investigates, by means of numerical simulations, extreme mechanical force exerted by a turbulent flow impinging on a bluff body, and examines the relevance of two distinct rare-event (...)
Article dans Atmosphere (2020)
Henri Lam, Alexandre Delache & Fabien Godeferd
We consider the separation of motion related to internal gravity waves and eddy dynamics in stably stratified flows obtained by direct numerical simulations. The waves’ dispersion relation links (...)
Article dans J. Fluid. Mech. (2020)
Aurélien Vadrot, Alexis Giauque & Christophe Corre
This study investigates the effects of a Bethe–Zel’dovich–Thompson (BZT) dense gas (FC-70) on the development of a turbulent compressible mixing layer at a convective Mach number $M_c=1.1$. (...)
Article dans Journal of Turbulence (2020)
Le Fang, T. Wu & Wouter Bos
It is illustrated that a sharply truncated initial kinetic energy spectrum evolves to a staircase-shaped spectrum at short times. This effect is directly associated with the triadic nature of the (...)
Article dans Phys. Rev. E (2020)
Benjamin Kadoch, Wouter Bos & Kai Schneider
A turbulent flow mixes in general more rapidly a passive scalar than a laminar flow does. From an energetic point of view, for statistically homogeneous or periodic flows, the laminar regime is (...)
