 Postdoc-Project:
Drop-flowing-film interaction
- Period:
2010-01-01 -- 2012-05-31
- Fellowship:
SINTEF
Energy Research, Low-emission LNG systems.
- Sponser:
The partners GDF SUEZ,
Statoil and the Petromaks programme of the Research Council of Norway (193062/S60).
- Description:
Droplets
impinge with a flowing liquid film of various
angles, thickness and velocities. The investigation will give insight
information on droplet behaviours in the
phase-separation units in LNG systems, as well as in other
applications, with more application-geared experimental-conditions.
