An analytical solution of Shallow Water system coupled to Exner equation
Christophe Berthon, Stéphane Cordier, Minh H. Le +1
In this paper, an exact smooth solution for the equations modeling the bedload transport of sediment in Shallow Water is presented. This solution is valid for a large family of sed…
Large bubble rupture sparks fast liquid jet
Thomas Séon, Arnaud Antkowiak
This Letter presents the novel experimental observation of long and narrow jets shooting out in disconnecting large elongated bubbles. We investigate this phenomenon by carrying ou…
Sensitivity analysis and determination of free relaxation parameters for the weakly-compressible MRT-LBM schemes
Hui Xu, Orestis Malaspinas, Pierre Sagaut
It is well-known that there exist several free relaxation parameters in the MRT-LBM. Although these parameters have been tuned via linear analysis, the sensitivity analysis of thes…
Sur une généralisation de l'opérateur fractionnaire
Thomas Michelitsch, Gérard Maugin, Shahram Derogar +2
The goal of this communication is to propose a generalized notion of the "traditional derivative". This generalization includes the fractional derivatives such as the Riemann-Liouv…
Cross-waves induced by the vertical oscillation of a fully immersed vertical plate
F. Moisy, G. -J. Michon, M. Rabaud +1
Capillary waves excited by the vertical oscillations of a thin elongated plate below an air-water interface are analyzed using time-resolved measurements of the surface topography.…
Non Classical Rotational Inertia Fraction in a One Dimensional Model of Supersolid
Néstor Sepulveda, Christophe Josserand, Sergio Rica
We study the rotational inertia of a model of supersolid in the frame of the mean field Gross-Pitaevskii theory in one space dimension. We discuss the ground state of the model and…
