The pipeline leakage process of supercritical CO2 involves complex phenomena because of the high inner pressure and the multiphase choked flow near the leakage point. In this work, an experimental facility was developed to investigate the thermodynamic and fluid dynamic behaviour in pressurized...

Three-dimensional numerical simulations are performed to investigate the effects of nitrogen (N2) and sulfur dioxide (SO2) impurities on the solubility trapping mechanism of carbon dioxide (CO2) geological storage. Dissolved CO2 has been suggested to increase the density of the aqueous phase....

The accidental release is one of the main risks during the pipeline transportation of supercritical CO2 for carbon capture and storage and enhanced oil recovery. The leakage of high pressure CO2 involves complex phenomena, including the expansion and flashing of the CO2 jet, dispersion of a...

Effective monitoring and numerical simulations are essential to understanding the implications of long-term geological carbon storage; in particular, the predictions of CO2 plume flow under storage conditions, storage integrity of sites, and the design and operational aspects of the CO2 storage...
