Abstract:

The present work deals with the modelling of turbulent air-water flows, where the phases are separated by a deformable, but non-broken interface. We use a “mesoscopic” level of description, i.e. we aim to model the probabilty $\alpha$ of finding the water phase at a given point of the flow. The evolution equation for the function $\alpha$ is solved with the use of the conservative level-set method.
