Lamellar ordering, droplet formation and phase inversion in exotic active emulsions
Francesco Bonelli, Livio Nicola Carenza, Giuseppe Gonnella +3
We study numerically the behaviour of a mixture of a passive isotropic fluid and an active polar gel, in the presence of a surfactant favouring emulsification. Focussing on paramet…

Cavitation inception of a van der Waals fluid at a sack-wall obstacle
G. Kaehler, F. Bonelli, G. Gonnella +1
Cavitation in a liquid moving past a constraint is numerically investigated by means of a free-energy lattice Boltzmann simulation based on the van der Waals equation of state. The…

Self-induced density modulations in the free expansion of Bose-Einstein condensates
L. Salasnich, N. Manini, F. Bonelli +2
We simulate numerically the free expansion of a repulsive Bose-Einstein condensate with an initially Gaussian density profile. We find a self-similar expansion only for weak inter-…
