Modeling of Flows with Interfaces

Flows with interfaces exhibit interactions on a large range of scales, resulting in large demands on compute power for simulations. Single-phase flows already can exhibit a large range of strongly coupled scales whose efficient computational modeling poses a challenge by itself. Immersed interfaces add small-scale transport phenomena and can dominate the overall flow evolution.

A challenge is to develop numerical models that take into account required computational efficiency for the particular cased under consideration. We will present three approaches for efficient modeling interfacial phenomena in flows, that are well suited for a particular range of applications:

Eulerian sharp interface and smooth interface models and Lagrangian particle methods.

The fundamental concepts for each approach are presented, strengths and weaknesses are discussed and recent developments out of our modeling group are presented on examples.
