Demonstration of a multi-field approach for different scales of interfacial structures
Demonstration of a multi-field approach for different scales of interfacial structures
Hänsch, S.
A new concept for generalized two-phase flows (GENTOP) is presented which combines the idea of the inhomogeneous MUSIG-model and the AIAD-approach. It is used for the simulation of transitions between multi-scale interfacial structures. It is demonstrated using three different exemplary cases: the impinging jet with air entrainment, a bubble column and the dambreak case with an obstacle. Main principles are introduced and recent developments on this concept are presented, including a new source term for sub-grid wave turbulence.
