The numerical investigation of supercritical two phase fluid flow in support of carbon dioxide storage

The lattice Boltzmann method (LBM) has its unique advantage in processing complex structure of physical model and is also an effective simulation method of studying two phase fluid flow to capture the interface. This paper is aimed to illustrate the principle of Shan-Chen model, theoretical analysis and the results involving carbon dioxide storage process. The results show that the data calculated by Shan-Chen model has a good agreement with Laplace's law, also according with the analytical velocity profile and relative permeability curve of two phase laminar flow. During the process of carbon dioxide storage, a high rate of injection will increase the amount of residual capture of carbon dioxide as well as decrease the amount of chemical capture.
