OLGA
OLGA fails to predict the separation of the phases when the emulsion breaks
How to tackle this issue? Start-up after cooldown non- representative of real system
- Initial Conditions for start-up
- Plugs in system (oil and water allowed to separate)
- Complex Fluid Module
Is core annular flow scalable?

High Viscosity or Shear Thinning or High Yield Stress
Bingham, Power law or Newtonian (High Viscosity)
- This method will significantly improve the results and the accuracy
- f the model;
- It requires trial and error to benchmark results with lab data
(viscosity) to define the yield stress/consistency factor.
