Hi, everyone, I want to simulate the water-gas-oil three phases flow in a tank. There is a tank with a height of 1m, 0.8m for water and 0.2m for oil. The gas is injected into the tank from the nozzle (r=0.05m, v=0.5m/s) at the center of the bottom. It is better to reflect the bubble column and free surface flow between water and oil simultaneously. Anyone has the experience to simulate this process using CFX software?

Actually, I have known how to model this process using the E-L approach. But at this time, I want to use the E-E approach to simulate. As we known, it is very easy to simulate the water-gas flow in a tank. The Particle Model in CFX can be achieved with the degassing condition. But when the oil is added into the system, how to model it? How to deal with the oil phase? Dispersed fluid or continuous fluid? How to deal with the outlet at this time? Is it still used the degassing condition in model? or use the other opening outlet for instead? According my previous thought, I tried to use the Particle Model for water-gas, and the Free Surface Model for water-oil, in conjuction with a proper turbulence model. Unfortunately, error, error, error!
