Fluid Mechanics

Research:

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 gas and oil 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 hydrophobic coatings

Complex flow phenomena
Fluid-solid dynamics of asphaltene deposition in oil wells
Bubble transport in pipelines filled with viscous liquid
Multiphase flow at splitters

The work is carried out at 3ME in collaboration with other faculties, with industries (e.g. Shell, ENI), and with technology institutes (e.g. TNO, Deltares, Dynaflow Research). Master students that do their thesis work on this topic, can do (part of) their research work outside de university in industry or at a technology institute.
