Title:Lagrangian coordinates and splitting technique for two phase flow models
Seminar:Hyperbolic and Mixed Type PDEs Seminar
Speaker:Wen Shen, Penn State University
Abstract:
In this talk we will look at several models arising in modeling of two phase flow in reservoir simulation. Based on fluid dynamic principle, the effects of the thermodynamics and hydrodynamics should be independent of each other. We will use a specific Lagrangian coordinate, and observe that, transform into this new coordinate system, the system is decoupled, where one equation describes the thermodynamics, while the other for the hydrodynamics. Furthermore, we show that entropy weak solutions are equivalent in these two different coordinate systems.
