On the Consistency of Dynamic Wetting Boundary Conditions for the Navier-Stokes-Cahn-Hilliard Equations

T. H. B. Demont, S. K. F. Stoter, C. Diddens +1

We investigate the limiting behavior of the Navier-Stokes-Cahn-Hilliard model for binary-fluid flows as the diffuse-interface thickness passes to zero, in the presence of fluid-flu…

Stabilized immersed isogeometric analysis for the Navier-Stokes-Cahn-Hilliard equations, with applications to binary-fluid flow through porous media

Stein K. F. Stoter, Tom B. van Sluijs, Tristan H. B. Demont +2

Binary-fluid flows can be modeled using the Navier-Stokes-Cahn-Hilliard equations, which represent the boundary between the fluid constituents by a diffuse interface. The diffuse-i…

Critical time-step size analysis and mass scaling by ghost-penalty for immersogeometric explicit dynamics

Stein K. F. Stoter, Sai C. Divi, E. Harald van Brummelen +3

In this article, we study the effect of small-cut elements on the critical time-step size in an immersogeometric context. We analyze different formulations for second-order (membra…

A Robust and Accurate Adaptive Approximation Method for a Diffuse-Interface Model of Binary-Fluid Flows

T. H. B. Demont, G. J. van Zwieten, C. Diddens +1

We present an adaptive simulation framework for binary-fluid flows, based on the Abels-Garcke-Grün Navier-Stokes-Cahn-Hilliard (AGG NSCH) diffuse-interface model. The adaptive-refi…
