(Non)-universality of vortex reconnections in superfluids
Alberto Villois, Giorgio Krstulovic, Davide Proment
An insight into vortex reconnections in superfluids is presented making use of analytical results and numerical simulations of the Gross--Pitaevskii model. Universal aspects of the…
Wind generated rogue waves in an annular wave flume
A. Toffoli, D. Proment, H. Salman +7
We investigate experimentally the statistical properties of a wind-generated wave field and the spontaneous formation of rogue waves in an annular flume. Unlike many experiments on…
A Vortex Filament Tracking Method for the Gross-Pitaevskii Model of a Superfluid
Alberto Villois, Giorgio Krstulovic, Davide Proment +1
We present an accurate and robust numerical method to track quantized vortex lines in a superfluid described by the Gross-Pitaevskii equation. By utilizing the pseudo-vorticity fie…
Evolution of a superfluid vortex filament tangle driven by the Gross-Pitaevskii equation
Alberto Villois, Davide Proment, Giorgio Krstulovic
The development and decay of a turbulent vortex tangle driven by the Gross-Pitaevskii equation is studied. Using a recently-developed accurate and robust tracking algorithm, all qu…
Helicity within the vortex filament model
R. Hänninen, N. Hietala, H. Salman
Kinetic helicity is one of the invariants of the Euler equations that is associated with the topology of vortex lines within the fluid. In superfluids, the vorticity is concentrate…
Leapfrogging Kelvin waves
N. Hietala, R. Hänninen, H. Salman +1
Two vortex rings can form a localized configuration whereby they continually pass through one another in an alternating fashion. This phenomenon is called leapfrogging. Using param…
