Abstract:
The complex multiphase flow, in a new Gas-Liquid separator, was simulated using the SST k-ω
and Eulerian-Eulerian models. The flow split was imposed in the simulations using Outflow
boundary condition to mimic flow control in the real installation. Three cases were simulated to
assess the effects of different flow split on the separator performance and internal flow.
It was found that balancing the oil-in-gas and gas-in-oil entrainments simultaneously is difficult
to achieve. The flow split has no effect on the flow field upstream of the cone. Recirculation zones
develop in the annular space downstream of the cone and plays a key role in the separator
performance
