NUMERICAL MODELLING OF INTERMITTENCY REGION IN TURBULENT STRATIFIED AIR-WATER FLOWS etc15 Tracking Number 499Presentation: Session: Multiphase and non-Newtonian flows 1 Room: Room G Session start: 13:30 Wed 26 Aug 2015 Marta Waclawczyk martaw@fdy.tu-darmstadt.de Affifliation: Dr Tomasz Waclawczyk waclawczyk@fnb.tu-darmstadt.de Affifliation: Dr Topics: - Turbulence in multiphase and non-Newtonian flows 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. |
