CONCLUSIONS and FURTHER DEVELOPMENT
A new Eulerian-Eulerian three-phase solver was proposed for the preliminary analysis of the
separation process inside an Oil&Gas separator. The mathematical formulation of the governing
equations and the closure relations were specifically chosen to numerically capture phase
separations and phase inversion phenomena. The numerical algorithm was specifically designed to
ensure the boundness of the solutions and to enhance the implicit treatment of source terms.
The solver shows good agreement with the analytical multiphase benchmarks. Moreover, it provides
consistent results in terms of separation effectiveness in the simplified geometry of industrial oil and
gas separators.
As further developments, we are currently working on three aspects:
1. Perform additional simulations a real-case geometry using different inlet nozzle shapes;
2. Compare the CFD results with the industrial validation procedure;
3. Study the reduction of the computational cost of the code introducing a simplifying solver for
describing the separation process.
