Asymmetric lattice Boltzmann model for shallow water flows

Sujet: shallow water equation, fluvial-torrential transition, lattice Boltzmann, Galilean transformation, [SPI.AUTO] Engineering Sciences [physics]/Automatic, [SPI.MECA.MEFL] Engineering Sciences [physics]/Mechanics [physics.med-ph]/Fluids mechanics [physics.class-ph]

Résumé: We consider a Galilean transformation of the lattice Boltzmann model for shallow water flows. In this new reference frame, the velocity lattice is asymmetrical but it is possible to simulate flows with Froude number larger than 1 and to model the transition from a torrential to a fluvial regime.
