Multiphysics and Multiscale for Energy and Environmental Modeling

8:30 AM-9:15 AM
New Hampshire Ballroom
Chair: Steven F. Ashby, Lawrence Livermore National Laboratory

The speaker will discuss the formulation and numerical simulation of coupling multicomponent multiphase flow problems in the subsurface. The governing equations describe flow and transport in a porous reservoir which can be decomposed into several parts, based on the number and type of fluids which flow there. Each part is associated with a physical model which comprises a set of conservation equations, constitutive laws and a numerical algorithm implemented. The physical model codes are coupled across interfaces by a set of matching or approximately matching conservation equations and constitutive laws. In particular, we discuss the coupling of three, two, and single phase flow models. Extensions to couplings with surface water will be also discussed.
