Primary instability of a shear-thinning film flow down an incline : experimental study

Article dans J. Fluid Mech. (2017)

Primary instability of a shear-thinning film flow down an incline : experimental study

M. H. Allouche, V. Botton, S. Millet, D. Henry, S. Dagois-Bohy, B. Güzel, H. Ben Hadid

The main objective of this work is to study experimentally the primary instability of non-Newtonian film flows down an inclined plane. We focus on low-concentration shear-thinning aqueous (...)

Directional change of fluid particles in two-dimensional turbulence and of football players

Article dans Phys. Rev. Fluids (2017)

Directional change of fluid particles in two-dimensional turbulence and of football players

Benjamin Kadoch, Wouter J. T. Bos, and Kai Schneider

Multiscale directional statistics are investigated in two-dimensional incompressible turbulence. It is shown that the short-time behavior of the mean angle of directional change of fluid (...)

Mass conservation and reduction of parasitic interfacial waves in level-set methods for the numerical simulation of two-phase flows : A comparative study

Article dans Int. J. Multiph. Flow (2017)

Mass conservation and reduction of parasitic interfacial waves in level-set methods for the numerical simulation of two-phase flows : A comparative study

Zlatko Solomenko, Peter D.M. Spelt, Lennon Ó Náraigh, Pascal Alix

A commonly used class of methods for the numerical simulation of two-phase flows is level set. It is often reported though that this method does not accurately conserve mass of each fluid, unlike (...)

Subgrid-scale scalar flux modelling based on optimal estimation theory and machine-learning procedures

Article dans J. Turbul. (2017)

Subgrid-scale scalar flux modelling based on optimal estimation theory and machine-learning procedures

A. Vollant, G. Balarac, C. Corre

New procedures are explored for the development of models in the context of large eddy simulation (LES) of a passive scalar. They rely on the combination of the optimal estimator theory with (...)

Algebraic disturbances and their consequences in rotating channel flow transition

Article dans Phys. Rev. Fluids (2017)

Algebraic disturbances and their consequences in rotating channel flow transition

Sharath Jose, Vishnu Kuzhimparampil, Benoît Pier, and Rama Govindarajan

It is now established that subcritical mechanisms play a crucial role in the transition to turbulence of nonrotating plane shear flows. The role of these mechanisms in rotating channel flow is (...)

Reynolds and Prandtl number scaling of viscous heating in isotropic turbulence

Article dans Phys. Rev. Fluids (2017)

Reynolds and Prandtl number scaling of viscous heating in isotropic turbulence

Andrey Pushkarev, Guillaume Balarac, and Wouter J. T. Bos

Viscous heating is investigated using high-resolution direct numerical simulations. Scaling relations are derived and verified for different values of the Reynolds and Prandtl numbers. The (...)

Hybrid simulation combining two space–time discretization of the discrete-velocity Boltzmann equation

Article dans J. Comput. Phys. (2017)

Hybrid simulation combining two space–time discretization of the discrete-velocity Boltzmann equation

Jan Tobias Horstmann, Thomas Le Garrec, Daniel-Ciprian Mincu, Emmanuel Lévêque

Despite the efficiency and low dissipation of the stream-collide scheme of the discrete-velocity Boltzmann equation, which is nowadays implemented in many lattice Boltzmann solvers, a major (...)
