Effect of Liquid-Gas Interaction on Plume Structure in Blowout Flow

Multiphase flow simulation for oil and gas blowout in water is performed to investigate the effect of liquid-gas interaction on the plume structure. The mass and momentum balance equations were solved for each phase, and the interactions were considered with the Euler-Euler approach. To consider the interphase interaction between two dispersed phases in the oil-gas-water three-phase system, we applied the drag force between oil and gas in the momentum equation. A series of numerical results showed that the interaction between the two dispersed phases affected the velocity distribution of the gas and oil phases in the multiphase plume. These results suggested that the gas-oil interaction might affect the traveling time of gas and oil in an actual marine environment.
