The multiphase flow in pipelines is rather complex, and various flow regimes can occur ranging from well structured stratified flow to irregular slug flow. In the fluid flow lab the fundamental fluid mechanics of multiphase flow in pipelines are studied to answer practical problems appearing in the energy production industry, as well as in other industries (such as food, nuclear, civil). Models are being developed, ranging from approximating mechanistic models to a more complete approach with Computational Fluid Dynamics. Research items include:
Computational Fluid Dynamics for multiphase flow
New numerical schemes and solvers for the one-dimensional flow equations
New numerical schemes for 3D modeling of flow instabilities and slugs
Liquid accumulation at low gas flow
PIV experiments in a pipe with a low bend
Deliquification of gas wells using foamers
Deliquification of gas wells using an annulus
Complex flow phenomena
Pipeline cleaning with ball pigs or speed-controlled pigs
Turbulence and waves at liquid-liquid interfaces
Two-phase phenomena for CO2 transport and storage
The work is carried out at 3mE in collaboration with other faculties, with industries (e.g. Shell), and with technology institutes (e.g. TNO, Deltares, CWI, Dynaflow Research). Master students who do their thesis work on this topic, can do (part of) their research work outside the university in industry or at a technology institute.
