Diffuse Interface Models for Two-Phase Flows of Incompressible Fluids and Their Sharp Interface Limits
Date: 12/05/2019, 12:00 PM - 2:00 PM
Category: Veranstaltung
Location: Hubland Nord, Geb. 40, 40.03.003
Organizer: Lehrstuhl für Mathematik VI (Mathematik in den Naturwissenschaften)
Speaker: Helmut Abels

We will discuss so-called ”diffuse interface models” for the flow of two viscous incompressible Newtonian fluids in a bounded domain. Such models were introduced to describe the flow when singularities in the interface, which separates the fluids, (droplet formation/coalescence) occur. The fluids are assumed to be macroscopically immiscible, but a partial mixing in a small interfacial region is assumed in the model. Such kind of models became popular during the last decade for theoretical as well as numerical studies. We will give an overview of known analytic results on well-posedness and will discuss recent results on convergence of diffuse to sharp interface models.
