Article dans Int. J. High Perform. Comput. Appl. (2017)
Anne Cadiou, Marc Buffat, Bastien Di Pierro, Lionel Le Penven, Christophe Pera
Massively parallel simulations generate increasing volumes of big data, whose exploitation requires increasingly large storage resources, efficient networking technologies and post-processing (...)
Article dans J. Crystal Growth (2017)
Mokhtar Ben Sassi, Slim Kaddeche, Marcello Lappa, Séverine Millet, Daniel Henry, Hamda Ben Hadid
The effect of thermodiffusion on dopant distribution in the melt and in the grown crystal is investigated numerically for a vertical Bridgman configuration for situations of pure thermal (...)
Article dans Comput. Fluids (2017)
Wouter J.T. Bos, Robert Rubinstein
Recent numerical results show that if a scalar is mixed by periodically forced turbulence, the average mixing rate is directly affected for forcing frequencies small compared to the integral (...)
Article dans J. Fluid Mech. (2017)
A. Venaille, L. Gostiaux and J. Sommeria
Predicting how much mixing occurs when a given amount of energy is injected into a Boussinesq fluid is a long-standing problem in stratified turbulence. The huge number of degrees of freedom (...)

Simulations using a Restricted Nonlinear (RNL) system, where mean flow distortion resulting from Reynolds stress feedback regenerates rolls, is applied in a channel flow under subcritical (...)
Article dans Comput. Fluids (2017)
Claude Cambon, Vincent Mons, Benoît-Joseph Gréa, Robert Rubinstein
We show how two-point turbulence models based on triadic closures, initially developed for homogeneous isotropic turbulence, can be applied to anisotropic turbulent flows. Efficient numerical (...)
Article dans Chin. J. Aeronauti. (2017)
Gao Feng, Ma Wei, Sun Jinjing, Jérôme Boudet, Xavier Ottavy, Liu Yangwei, Lu Lipeng, Shao Liang
Large-eddy simulation (LES) is compared with experiment and Reynolds-averaged Navier-Stokes (RANS), and LES is shown to be superior to RANS in reproducing corner separation in the LMFA-NACA65 (...)
Article dans Wave Motion (2017)
J.F. Scott, P. Blanc-Benon, O. Gainville
Multiple-scale asymptotic analysis is applied to small-wavelength, weakly nonlinear propagation of an impulsive acoustic wave in a general (3D, in-motion and time dependent) atmosphere. In (...)
Article dans Phys. Rev. Fluids (2017)
Aurore Loisy and Aurore Naso
The free rise of isolated, deformable, finite-size bubbles in otherwise homogeneous isotropic turbulence is investigated by direct numerical simulation. The Navier-Stokes equations are solved in (...)
Article dans J. Fluid Mech. (2017)
Benoît Pier and Peter J. Schmid
The dynamics of small-amplitude perturbations, as well as the regime of fully developed nonlinear propagating waves, is investigated for pulsatile channel flows. The time-periodic base flows are (...)
