Multi-Scale Modelling Techniques - GENTOP

Multi-Scale Modelling Techniques - GENTOP

Lucas, D.; Hänsch, S.

In multiphase flows interfaces may span over a wide range of sizes. In a multi fluid approach interfaces smaller as well as larther than the typical size of the numerical grid may occur. While the small interfaces (bubbles and drops) should be represent by smeared phase volume fractions the large structures should be resolved in a CFD simulation. Also transitions between contineous and dispersed morphologies of teh phases may occur.
The lecture discusses the issues for modelling such flows and the basic ideas of the GENTOP concept. Domonstration simulations using the GENTOP concept show the cpabablities of this approach.
