Error analysis for a viscoelastic phase separation model

Aaron Brunk, Herbert Egger, Oliver Habrich +1

We consider systematic numerical approximation of a viscoelastic phase separation model that describes the demixing of a polymer solvent mixture. An unconditionally stable discreti…

Variational approximation for a non-isothermal coupled phase-field system: Structure-preservation & Nonlinear stability

Aaron Brunk, Oliver Habrich, Timileyin David Oyedeji +2

A Cahn-Hilliard-Allen-Cahn phase-field model coupled with a heat transfer equation, particularly with full non-diagonal mobility matrices, is studied. After reformulating the probl…

A second-order structure-preserving discretization for the Cahn-Hilliard/Allen-Cahn system with cross-kinetic coupling

Aaron Brunk, Herbert Egger, Oliver Habrich

We study the numerical solution of a Cahn-Hilliard/Allen-Cahn system with strong coupling through state and gradient dependent non-diagonal mobility matrices. A fully discrete appr…

A second-order fully-balanced structure-preserving variational discretization scheme for the Cahn-Hilliard Navier-Stokes system

Aaron Brunk, Herbert Egger, Oliver Habrich +1

We propose and analyze a structure-preserving space-time variational discretization method for the Cahn-Hilliard-Navier-Stokes system. Uniqueness and stability for the discrete pro…

On uniqueness and stable estimation of multiple parameters in the Cahn-Hilliard equation

Aaron Brunk, Herbert Egger, Oliver Habrich

We consider the identifiability and stable numerical estimation of multiple parameters in a Cahn-Hilliard model for phase separation. Spatially resolved measurements of the phase f…

Relative energy estimates for the Cahn-Hilliard equation with concentration dependent mobility

Aaron Brunk, Herbert Egger, Oliver Habrich +1

Based on relative energy estimates, we study the stability of solutions to the Cahn-Hilliard equation with concentration dependent mobility with respect to perturbations. As a by-p…
