Enhanced interface dynamics in second-order Cahn-Hilliard models: A comparative analysis with applications to convection-diffusion
Original language description
This paper presents a numerical investigation of various formulations of the Cahn–Hilliard (CH) equation for phase separation in binary mixtures. By comparing first- and second-order CH formulations across a suite of diffusive and convective test cases, we demonstrate that second-order models not only produce sharper diffuse- and convective-interface representations but also substantially accelerate phase separation, enabling more rapid attainment of pure-phase states. A key contribution is the development of efficient, unconditionally energy stable numerical scheme for the doubly-degenerate second-order model, implemented in OpenFOAM and applied to convection–diffusion problems. Future work will address coupling of the model with the Navier–Stokes (NS) equations to capture full two-phase flow dynamics despite necessary modifications to the chemical potential.
