Recent Methods Developments for Modeling
Interfacial Flows

Dr. Marianne Francois

Interfacial flows are multi-material flows comprised of two or more immiscible materials demarcated by interfaces. They are ubiquitous in nature and are encountered in several industrial applications, such as in additive manufacturing and in inertial confinement fusion. We are interested in the development of accurate numerical methods for high-fidelity simulations of interfacial flows. The volume tracking method, also known as the volume-of-fluid method has become an established numerical approach to model and simulate interfacial flows. Its advantage is its strict mass conservation. However, because the interface is not explicitly tracked but captured via the material volume fraction on a fixed mesh, accurate estimation of the interface position, its geometric properties and modeling of interfacial physics in the volume tracking framework remain difficult. Several improvements have been made over the last decade to address these challenges. In this talk, I will discuss some of our recent work in interface reconstruction and show some new development for the modeling of additive manufacturing processes.
