Three-dimensional phase field modeling of inhomogeneous gas-liquid systems using the PeTS equation of state

Abstract: Recently, an equation of state (EoS) for the Lennard-Jones truncated and shifted (LJTS) fluid has become available. As it describes metastable and unstable states well, it is suited for predicting density profiles in vapor-liquid interfaces in combination with density gradient theory (DGT). DGT is usually applied to describe interfaces in Cartesian one-dimensional scenarios. In the present work, the perturbed LJ truncated and shifted (PeTS) EoS is implemented into a three-dimensional phase field (PF) model whi… Show more

“…The lower computational effort of the PF simulations compared to MD simulations enables the model to simulate wetting scenarios on the microscale. The present phase field (PF) model represents a coupling of the static PF model described in [1] with the compressible Navier-Stokes equations, cf. [2].…”
