Smoothed Particle Hydrodynamics: Pore-Scale Numerical Simulation of Supercritical CO2 Injection

A pore-scale simulation capability, paralleling PNNL’s microfluidics experimental capability, has also been developed. The capability is built on the Smoothed Particle Hydrodynamics (SPH) methodology and is implemented within a scalable computational framework (Palmer et al. 2010) to take advantage of high-performance computing capabilities available at PNNL and around the U.S. Department of Energy complex. The combined numerical and experimental capability provides a powerful toolset for analysis of pore-scale problems. The numerical model can be used to support design of physical experiments, and it can extend those experiments to a broader range of cases than can be implemented physically. The experimental data provide data for validating and testing the numerical model capabilities, as shown in the figure below.
