Acoustic Analogy for Multiphase or Multicomponent Flow

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...

\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...

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...

Parallel computation for reservoir thermal simulation of multicomponent and multiphase fluid flow

We consider parallel computing technology for the thermal simulation of multicomponent, multiphase fluid flow in petroleum reservoirs. This paper reports the development and applications of a parallel thermal recovery simulation code. This code utilizes the message passing interface (MPI) library, overlapping domain decomposition, and dynamic memory allocation techniques. Its efficiency is inve...
