Stick-slip-to-stick transition of liquid oscillation in a U-tube
Alessandro Bongarzone, François Gallaire
The nonlinear decay of oscillations of a liquid column in a U-shaped tube is investigated within the theoretical framework of the projection method formalized by Bongarzone et al.…

Swirling against the forcing: evidence of stable counter-directed sloshing waves in orbital-shaken reservoirs
Alice Marcotte, François Gallaire, Alessandro Bongarzone
We study the free surface response in a cylindrical container undergoing an elliptic periodic orbit. For small forcing amplitudes and deep liquid layers, we quantify the effect of…

Numerical estimate of the viscous damping of capillary-gravity waves: A macroscopic depth-dependent slip-length model
Alessandro Bongarzone, Francois Gallaire
We propose a numerical approach to regularize the contact line singularity appearing in the computation of viscous capillary-gravity waves with moving contact line in cylindrical c…
