Abstract: This study focuses on CO2 storage by investigating CO2 flow in deep underground porous media, within the framework of the major current issue on carbon dioxide capture and storage (CCS). Our project intends to simulate CO2 flow in porous media using the Lattice Boltzmann Model (LBM). The LBM is a discrete computational method based upon the Boltzmann equation. It considers a fundamental volume of fluid to be composed of a collection of particles. Each set of particles contained in these volumes is represented by a particle velocity distribution function for each fluid component at each grid point. During the time-step advance of the simulation, the fluid particles can collide with each other as they move, possibly under applied forces. The rules governing the collisions, such as Bhatnagar-Gross-Krook (BGK) are designed such that the time-averaged motion of the particles is consistent with the Navier-Stokes equation (Chen and Doolen 1998).

LBM is a mesoscopic method which is able to capture microscopic effects and reproduces macroscopic behavior of fluids as a result (Huang et al. 2014).

The aim of the 3+3 year project is to thoroughly investigate the LBM ability to handle multiphase multicomponent (specifically CO2-brine system) flows in porous media, using current state-of-the-art multiphase models and envision potential improvements in treating the interface such that the model can better accommodate the specific application.

In the presentation, Professor will give an overview of LBM and its mathematical-physical characteristics, as well as some examples of the progress of my research team in using LBM for multiphase flow modeling in meso-scale domains, in our progressive approximation to the more realistic conditions as those found in aquifers where CO2 is typically targeted to be stored.
