Abstract: Dr. Tartakovsky 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-Landau-Lifshitz-Navier-Stokes (LLNS) equation. He will discuss grid-based and meshless discretizations of the resulting stochastic partial differential equations. His 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).
Bio: Dr. Alexandre Tartakovsky is a Laboratory Fellow and Team Lead in the Computational Science and Mathematics Division at the Pacific Northwest National Laboratory. The main focus of Dr. Tartakovsky’s research is the theoretical and computational aspects of the modeling of flow and reactive transport in porous and fractured media under both saturated and unsaturated conditions. In Dr. Tartakovsky’s research in the subsurface flow and transport phenomena, he pursues a multi-disciplinary approach and relies on methods and techniques used in hydrology, mathematics, computational physics, and chemical engineering.
