Title: Energetic Variational Approaches (EnVarA) for Active Materials and Reactive Fluids
Abstract: Active materials and reactive fluids consists of those materials that consume or convert energy to generate motion and deformations. They are involved in many biological activities and in most time, the principle characteristics of living organisms. In this talk, we will present a derivation and generalization of the mass action kinetics of chemical reactions using an energetic variational approach.
The method enables us to capture the coupling and competition of various mechanisms, including mechanical effects such as diffusion, viscoelasticity in polymerical fluids and muscle contraction, as well as the thermal effects.
We will also discuss several applications under this approach, in particular, the modeling of wormlike micellar solutions.
This is a joint work with Bob Eisenberg, Pei Liu, Yiwei Wang and Tengfei Zhang.
