Andrea Giorgini, Kei Fong Lam, Elisabetta Rocca, Giulio Schimperna

摘要:

本文研究了描述Hele-Shaw盒中二元流体流动演化的扩散界面模型。该模型由具有输运和质量源的Cahn-Hilliard-Darcy(CHD)型系统组成。相关的物理应用与肿瘤生长动力学有关,这特别证明了大量流入的发生。研究了该模型的初边值问题,证明了二维空间中整体强解的存在唯一性和三维空间中局部解的存在性。

英文摘要:

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 (CHD) 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.
