Non-local Mesoscale Model for Multiphase Flow

I will present a novel non-local mesoscale model for multiphase flow. The model is obtained by adding a non-local “surface-tension” force to the Landau-Lifshitz-Navier-Stokes equation. Next, I will discuss grid-based and meshless discretizations of the resulting stochastic partial differential equations. Our results show that the proposed mesoscale model is able to recover molecular-scale features (including thermally-driven interface fluctuations and curvature-dependent surface tension) and macroscale behavior (such as the Young-Laplace law).
