To anticipate the dynamics of the bubble plume, its dissolution into the water column, and the resulting change in seawater pH and pCO2, it is necessary to create a multiphase model to simulate a CO2 leak from a potential pipeline rupture. A geological feature in Texas is ideal for CO2 sequestration. The ecology and maritime traffic safety would be at risk if a CO2 reservoir or transmission pipeline were to leak. The present study introduces an Eulerian-Eulerian computational fluid dynamics model in Ansys Fluent software, where the simulation has been done in 3D for validation studies and in 2D for the Gulf of Mexico 50m case. The physical and chemical processes involved, such as buoyancy, turbulence, and gas dissolution kinetics, are all considered. The mass transfer coefficient is estimated using the Hughmark correlation. Seawater temperature and salinity are used for estimating Dissociation and Henry's Law constant. The model is validated using QICS and Hauser Tank Experiment. Hypothetical CO2 release from High Island 10L was simulated and compared to Oldenburg and Pan's work. Findings indicate that the water column will nearly fully mitigate a significant CO2 release of 35 kg/s in 50 m of water due to CO2 absorption in seawater during ascent. The simulation aided in the comprehension of potential dangers related to the discharge.
