报告题目：Mathematical Models for Complex Fluids by Using Energy Variational Method
报告人：Shixin Xu（Duke Kunshan University）
摘要：Complex fluids are those with internal microstructures whose evolution affects the macroscopic dynamics of the material, especially the rheology. So it is a multiscale and multicomponent problem. Those internal microstructures interactions will induce some non-Newtonian mechanical properties, for example, viscoelasticity and strain stiffening. A lot of models have been proposed to model different types of complex fluids. In this talk, we will present the energetic variational approach by which the model is always thermal dynamic consistent. We will also talk about applications of energetic variation method on different scales of complex fluids.
