Abstract: The deposition of carbon dioxide (CO 2) into the marine geological structure has been considered as a good solution to deal with the global situation of CO 2 concentration increasing in the atmosphere nowadays. But during transporting, injecting and being stored in the geological structure, accidents cannot be avoided and CO 2 would be released to the surroundings. Liquid or gas CO 2 can react with sea water to form acid carbonic. That will yield to the increase of CO2concentration and lower p H value of ambient water. This process has a strong negative effect on the marine system. This paper, using the standard two equation k-? model, simulates the near-field study of liquid CO 2 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.
