Introduction
Understanding fluid transport in natural porous media is important for many industrial and scientific applications. Computer simulations require accurate three-dimensional microscopic structure data as input and efficient numerical algorithms for fluid flow simulations. Natural porous media such as carbonates and clay filled sandstones exhibit heterogeneities on many scales and cannot be modeled by existing modeling techniques.
Our Project
A continuum model is developed for generating synthetic microcomputer-tomography data of multiscale porous media at arbitrary resolution. Large scale parallelized lattice-Boltzmann simulations are performed to calculate transport parameters, such as permeabilities using Darcy's Law, and other material parameters.
Lattice Boltzmann Method
The Lattice Boltzmann method numerically solves the discretized Boltzmann equation using a linearized collision operator to simulate the flow of a Newtonian fluid. We use the D3Q19 lattice model together with a single relaxation time (BGK) or two relaxation time (MRT/TRT) collision operator. Extensive calibrations for or implementations were performed by simulating Poiseuille Flow in pipes of varying shapes and sizes.
