Nonlinear effects on interfacial wave growth into slug flow
Bryce Campbell ( bcampb at:mit dot'edu )

This work is focused on developing an efficient and robust CFD capability for the accurate prediction the hydrodynamics of multiphase flow through oil pipelines. For this, two unique computational capabilities are developed.

The first is a high order potential flow solver which is capable of simulating the nonlinear interfacial phenomena which occur over large scales within the pipeline (Pipe Length/Diameter ~10-10,000). This method is capable of simulating the formation (from a flat interface) and nonlinear evolution of large amplitude waves. Click on the link below to view free-surface evolution.


The second method is based on the solution of the three-dimensional Navier-Stokes equation in shorter length pipes (Pipe Length/Diameter ~1-10). By implementing an effective interface capturing scheme, physics-based turbulent flow/interface dissipation models can be developed and then be supplied to industrial code capabilities. This method is inherently capable of examining the small scale physics associated with transient multi-phase flows.


These two schemes are used to understand and characterize the mechanics of various flow patterns and mechanisms for the transition of the flow patterns under a variety of operation/geometric conditions.
