Model reduction for two-phase flow problems based on the Onsager variational principle

Speaker: XU Xianmin, associate professor of Institute of Computational Mathematics, Chinese Academy of Sciences.

Venue: 316, Ouyang Chunmei Building, Yuquan Campus

Abstract:

The Onsager variational principle is a fundamental law for irreversible processes in nonequilibrium statistical physics. It has been used to model many complicated phenomena in soft matter. In this talk, I will give a brief introduction of the principle. In particular, I will show it can be used as a powerful approximation tool for many complicated two-phase flow problems. It can be used to derive efficient numerical methods for wetting problems on inhomogeneous surfaces.
