内容摘要：

The CH-HS system which is used to describe the motion of a viscous fluid between two closely spaced parallel plates is a very important mathematical model. The CH-HS system can be derived from the Navier-Stokes in the Hele-Shaw cell . The CH-HS system is used in many different applications, such as the process of the phase separation, tumor growth, cell sorting and multi-phase flows in porous media. In this topic, the content is divided into three part: (1)Decoupled, energy stable numerical scheme for the Cahn-Hilliard -Hele-Shaw system with logarithmic Flory-Huggins potential,(2)Numerical Analysis for the Cahn-Hilliard-Hele-Shaw System with Variable Mobility and Logarithmic Flory-Huggins Poential.(3)Analysis of a novel finite element method for a modified Cahn-Hilliard-Hele-Shaw system.
