ON THE EXISTENCE OF STRONG SOLUTIONS TO THE CAHN-HILLIARD-DARCY SYSTEM WITH MASS SOURCE
SIAM JOURNAL ON MATHEMATICAL ANALYSIS(2022)
摘要
We study a diffuse interface model describing the evolution of the flow of a binary fluid in a Hele-Shaw cell. The model consists of a Cahn-Hilliard-Darcy type system with transport and mass source. A relevant physical application is related to tumor growth dynamics, which in particular justifies the occurrence of a mass inflow. We study the initial-boundary value problem for this model and prove global existence and uniqueness of strong solutions in two space dimensions as well as local existence in three space dimensions.
