The 3D strict separation property for the nonlocal Cahn-Hilliard equation with singular potential

A Poiatti - arXiv preprint arXiv:2303.07745, 2023 - arxiv.org
We consider the nonlocal Cahn-Hilliard equation with singular (logarithmic) potential and
constant mobility in three-dimensional bounded domains and we establish the validity of the …

[HTML][HTML] Global well-posedness and convergence to equilibrium for the Abels-Garcke-Grün model with nonlocal free energy

CG Gal, A Giorgini, M Grasselli, A Poiatti - Journal de Mathématiques Pures …, 2023 - Elsevier
We investigate the nonlocal version of the Abels-Garcke-Grün (AGG) system, which
describes the motion of a mixture of two viscous incompressible fluids. This consists of the …

Sharp interface limit for a Navier–Stokes/Allen–Cahn system with different viscosities

We consider a multi-component version of the conserved Allen–Cahn equation proposed by
J. Rubinstein and P. Sternberg in 1992 as an alternative model for phase separation. In our …

(Non-) convergence of solutions of the convective Allen–Cahn equation

H Abels - Partial Differential Equations and Applications, 2022 - Springer
We consider the sharp interface limit of a convective Allen–Cahn equation, which can be
part of a Navier–Stokes/Allen–Cahn system, for different scalings of the mobility m_ ε= m_0 …

Mathematical Analysis of a Diffuse Interface Model for Multi-phase Flows of Incompressible Viscous Fluids with Different Densities
