Parallel Simulation of Multiphase/Multicomponent Flow Models

The simulation of flow in porous media is a computationally demanding task. Thermodynamical equilibrium calculations and complex, heterogeneous geological structures normally gives a multiphysics/multidomain problem to solve. Thus, efficient solution methods are needed. The research simulator Athena is a 3D, multiphase, multicomponent, porous media flow simulator. A parallel version of the simu...

Multicomponent-Multiphase Equation of State for Carbon

The PANDA code is used to build a tabular equation of state (EOS) table for carbon. The model includes three solid phases (graphite, diamond, and metallic) and a fluid phase mixture containing three molecular components (C1, C2, and C3). Separate EOS tables were first constructed for each solid phase and for each molecular species in the fluid phase. Next, a mixture/chemical equilibrium model w...

\LDRD Final Report: Physical Simulation of Nonisothermal Multiphase Multicomponent Flow

This document reports on the accomplishments of a laboratory-directed research and development (LDRD) project whose objective was to initiate a research program for developing a fundamental understanding of multiphase multicomponent subsurface transport in heterogeneous porous media and to develop parallel processing computational tools for nwnerical simulation of such problems. The main achiev...

A Multicomponent and Multiphase Model of Reactive Wetting

A diffuse-interface model of reactive wetting with intermetallic formation is presented. The model incorporates fluid flow, solute diffusion, and phase change that are based on the total molar Gibbs energy of a ternary system with four phases. Numerical simulations were performed successfully revealing the complex behavior of the reactive wetting process that include nucleation and growth of an...
