IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

MODELING OF CO2 JET/PLUME IN DEEP SEA
Author : THAO NGUYEN(1), JIN HWAN HWANG(2)
The deposition of carbon dioxide (CO2) into the marine geological structure has been considered as a good solution to deal with the global situation of CO2 concentration increasing in the atmosphere nowadays. But during transporting, injecting and being stored in the geological structure, accidents cannot be avoided and CO2 would be released to the surroundings. Liquid or gas CO2 can react with sea water to form acid carbonic. That will yield to the increase of CO2 concentration and lower pH value of ambient water. This process has a strong negative effect on the marine system. This paper, using the standard two equation k-ɛ model, simulates the near-field study of liquid CO2 jet/plume. It will show the development and behavior of CO2 flow with the presence of background currents. It is also included the spatial evolution of a turbulent buoyant fluid driven by concentration difference. The results show that the verification of numerical data with theory agree well. And the modeling data of advected jet/plume characteristics both in longitudinal trajectory and transverse vortex pair bifurcation phenomenon are well supported by dimension analysis and other related experimental data.
