Multiphase Flow Technology Laboratory

- At NTNU Energy and Process Engineering 

Contact: Ole Jørgen Nydal

 

The Multiphase Flow Technology Laboratory serves fundamental studies related to transport of oil-water-gas mixtures in pipes. Several test sections (3-6 cm I.D., 17 long, 7 m high) are instrumented with impedance probes, pressure censors and moving camera for characterization of steady and transient flow conditions.

The loop is automated and is now possible to operate through a web site (NetLab).

Instrumentation

Impedance ring probes, absolute and dP pressure transducers

Configurations

1) Straight pipe, acrylic and transparent
2) Straight pipe, steel
3) S-riser, acrylic, transparent
4) L-riser, acrylic transparent
5) Flexible pipes for hilly terrain experiments
6) Pigging experiments

A transportable mini-loop is available for flow visualization. The mini-lop is a useful instrument for student exercises, and for demonstrations during lectures.

The laboratory was constructed in year 2001, and the following types of experiments have been made:

  • Characterization of unstable flow in S-shaped risers

  • Pigging in stagnant and flowing systems

  • Flow regime transitions, hysteresis effects

  • Oil-water and oil-water-air flows

  • Shut-down and startup transients

  • Unstable well flows

The laboratory has gained status as Marie Curie Training Site.
