Abstract
Summary
The growing concern about global warming has increased interests in geological storage of CO2. Investigating the risk of leakage of CO2 from injection sites (saline aquifers) is of great importance, because free CO2 has always a chance to leak out through pathways such as faults, fractures etc. Predicting the final fate of injected CO2 requires an understanding of the basics mechanisms involved in storage process. In this study, convective mixing, one of the main mechanisms during CO2 sequestration has been investigated numerically. Scaling analysis of convection parameters enables us to evaluate suitable injection sites without the need for costly simulations.
