Abstract

In this talk I will discuss a variety of gradient flow models for multi-phase problems, derived from an energy variational formulation. The models includes fractional differential equations, equations describing the interfacial dynamics of immiscible and incompressible two-phase fluids, dendritic crystal growth model, thermal phase change problems etc. The talk starts with a review of the models and numerical methods for these models. Then a new class of time-stepping schemes will be discussed.
