Flow Simulation in Stochastic Porous Media

Stochastic langevin model for flow and transport in porous media.

We present a new model for fluid flow and solute transport in porous media, which employs smoothed particle hydrodynamics to solve a Langevin equation for flow and dispersion in porous media. This allows for effective separation of the advective and diffusive mixing mechanisms, which is absent in the classical dispersion theory that lumps both types of mixing into dispersion coefficient. The cl...

In-Situ Data Compression for Flow Simulation in Porous Media

Supercomputing simulations easily generate datasets in the range of tera or even peta bytes. However, writing datasets during simulation and reading them for post-processing implies a high I/O load and thus imposes a major bottleneck. In the computation phase, compute nodes stall at writing large amounts of data and the simulation slows down scientists have to capture data less frequently losin...

Numerical Simulation of Three-Phase Flow in Heterogeneous Porous Media

We describe an efficient numerical simulator, based on an operator splitting technique, for three-phase flow in heterogeneous porous media that takes into account capillary forces, general relations for the relative permeability functions and variable porosity and permeability fields. Our numerical procedure combines a non-oscillatory, second order, conservative central difference scheme for th...

Mesoscopic Simulation of Rarefied Gas Flow in Porous Media

The accurate description of flow in nano-scale pores or channels is very important for the reliable design of materials and processes in the areas of MEMS, mesoporous media, and vacuum technologies. Use of classical flow equations fails in this regime since the continuum assumption is not valid. This is due to the fact that the mean free path is comparable to the characteristic dimensions of th...
