DOI: 10.1002/mma.5436
Abstract: We propose a simple model for a two‐phase flow with a diffuse interface. The model couples the compressible Navier‐Stokes system governing the evolution of the fluid density and the velocity field with the Allen‐Cahn equation… read more here.

DOI: 10.1007/s11538-019-00577-1
Abstract: We present a model for cell growth, division and packing under soft constraints that arise from the deformability of the cells as well as of a membrane that encloses them. Our treatment falls within the… read more here.

DOI: 10.1016/j.ijmultiphaseflow.2019.01.015
Abstract: Abstract Accurate and robust simulations of transcritical real-fluid flows are crucial for many engineering applications. Diffuse-interface methods are frequently employed and several numerical schemes have been developed for simulating transcritical flows. These schemes can be… read more here.

DOI: 10.1016/j.ijplas.2018.10.012
Abstract: Abstract In diffuse-interface (phase field) models of polycrystalline solids, the grain boundaries naturally possess a narrow region of finite thickness. A Ginzburg-Landau type kinetic equation for plastic deformation of a solid is derived that combines… read more here.

DOI: 10.1063/1.5113922
Abstract: A thermodynamically consistent diffuse interface model is developed for two-phase flows with phase transition. Inside the liquid-vapor mixing layer, the Cahn-Hilliard equation governing the evolution of liquid/vapor species explicitly includes the phase transition between the… read more here.

DOI: 10.1063/5.0027152
Abstract: The dynamics of a thin layer of liquid, squeezed between a flat solid substrate and an infinitely-thick layer of saturated vapor, are examined. The liquid and vapor are two phases of the same fluid, governed… read more here.

DOI: 10.1103/physreve.107.025104
Abstract: We elucidate the theoretical relationships among fundamental physical concepts that are involved in the diffuse interface modeling for an isothermal single-component liquid-vapor system, which cover both the equation of state (EOS) and the surface tension force.… read more here.

DOI: 10.1103/physrevfluids.3.094002
Abstract: We simulate a fluid droplet with suspended particles rising in another fluid with a diffuse interface model in which phase boundaries are replaced with smooth spreading interfaces. We find that at low Reynolds number the… read more here.
