The model is obtained by adding a non-local \u201csurface-tension\u201d force to the Landau-Landau-Lifshitz-Navier-Stokes (LLNS) equation. He\u00a0will discuss grid-based and meshless discretizations of the resulting stochastic partial differential equations. His\u00a0results 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).<\/span><\/p>\n<p class=\"p1\"><span class=\"s1\"><strong>Bio<\/strong>: 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&#8217;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&#8217;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.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>12:30 PM \u2013 1:30 PM on Monday, April 10, 2017, lunch served at 12:00 PM.
