A phase field model for tumour growth is introduced that is based on a Brinkman law for convective velocity fields. The model couples a convective Cahn-Hilliard equation for the evolution of the tumour to a reaction-diffusion-advection equation for a nutrient and to a Brinkman-Stokes type law for the fluid velocity. The model is derived from basic thermodynamical principles, sharp interface limits are derived by matched asymptotics and an existence theory is presented for the case of a mobility… 

Cahn-Hilliard-Brinkman models for tumour growth: Modelling, analysis and optimal control

Phase field models recently gained a lot of interest in the context of tumour growth models. In this work we study several diffuse interface models for tumour growth in a bounded domain with

Numerical analysis for a Cahn–Hilliard system modelling tumour growth with chemotaxis and active transport

A fully-discrete finite element approximation of the model and stability bounds for the discrete scheme are introduced and it is shown that discrete solutions exist and depend continuously on the initial and boundary data.

Existence of weak solutions to multiphase Cahn–Hilliard–Darcy and Cahn–Hilliard–Brinkman models for stratified tumor growth with chemotaxis and general source terms

Abstract We investigate a multiphase Cahn–Hilliard model for tumor growth with general source terms. The multiphase approach allows us to consider multiple cell types and multiple chemical species

Pressure jump and radial stationary solutions of the degenerate Cahn-Hilliard equation

The Cahn-Hilliard equation with degenerate mobility is used in several areas including the modeling of living tissues. We are interested in quantifying the pressure jump at the interface in the case

The Keller-Segel model is a well-known system representing chemotaxis in living organisms. We study the convergence of a generalized nonlinear variant of the Keller-Segel to the degenerate

From Vlasov equation to degenerate nonlocal Cahn-Hilliard equation

We provide a rigorous mathematical framework to establish the hydrodynamic limit of the Vlasov model introduced in [31] by Noguchi and Takata in order to describe phase transition of fluids by kinetic

Sharp-interface limits of the diffuse interface model for two-phase inductionless magnetohydrodynamic fluids

It is shown that the sharp interface limit of the models are the standard incompressible inductionless magnetohydrodynamic equations coupled with several different interface conditions for different choice of the mobilities.

Strong well-posedness and inverse identification problem of a non-local phase field tumour model with degenerate mobilities

We extend previous weak well-posedness results obtained in Frigeri et al. (2017, Solvability, Regularity, and Optimal Control of Boundary Value Problems for PDEs, Vol. 22, Springer, Cham, pp.
