It is important to predict biological impacts caused by the ocean sequestration of carbon dioxide (CO2). For this purpose, the dilution processes of CO2 should be understood in the deep ocean. A two-phase computational fluid dynamics (CFD) method with mass transfer was developed in order to predict droplet plume flow, the dissolution of CO2 from droplets into seawater, and the advection-diffusion of dissolved CO2 (DCO2). Change of pH due to the concentration of DCO2 is also calculated. In addition, a new mortality model was installed to predict the lethal damage of DCO2 to marine organisms. The simulation results suggest that the biological impacts of the CO2 sequestration can be insignificant in terms of mortality in business cases we proposed.
