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....

Numerical analyses are performed to study the fluid dynamic behaviours of the solubility trapping in the context of CO2 storage in deep geological formations. Dissolution of CO2 into the underlying brine increases the density of brine, leading to a gravitational instability. This instability...

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...

Numerical simulations are essential to the understanding of the long-term geological storage of CO2. Physical modelling of geological storage of CO2 has been based on Darcy’s law, together with the equations of conservation of mass and energy. Modelling and simulations can be used to predict...

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...

Genetic association studies are a powerful tool to detect genetic variants that predispose to human disease. Once an associated variant is identified, investigators are also interested in estimating the effect of the identified variant on disease risk. Estimates of the genetic effect based on...

As an emerging financial market, the trading value of carbon emission trading market has definitely increased. In recent years, the carbon emission allowances have already become a way of investment. They are bought and sold not only by carbon emitters but also by investors. In this paper, we...

The performance differences between the fluidized-bed and the fixed-bed operation modes were comparatively studied in a pressurized coal-fuelled chemical looping combustion (CLC) process. Pressurized thermogravimetric (TG) analysis was applied to elucidate the findings observed in pressurized...

We develop a probabilistic consumer choice framework based on information asymmetry between consumers and firms. This framework makes it possible to study market competition of several firms by both quality and price of their products. We find Nash market equilibria and other optimal strategies...
