Numerical modeling of Interface networks

Constant normal driven flow of an interface network with three regions at different time instance

Motivation and Objectives

Multi-region problems can occur when the motion of more than two immiscible fluids is to be described. In this case the interface network, separating the different fluid regions, evolves in time due to interactions of the different fluids across interface segments. These interactions often can be described by local fluid properties. Due to the complexity of the topology, numerical modeling the evolution and interactions near the interface network are long-standing challenges for the research community. 

Approach to Solution

We have developed a high-resolution transport formulation of the regional level-set approach for an improved prediction of the evolution of complex interface networks. The approach thus offers a viable alternative to previous interface-network level-set method.
