Experimental Facility

The gas liquid separation facility is installed within the Varmeteknisk Lab, EPT, NTNU. Details about the facility can be found in the Thermal Two Phase Flow Laboratory. Main Characteristics of the facility:





System Pressure



Mass flow rate


Test Lynx Prototype developed in the group. CEESI, USA, Dec. 2012. 60bar, hydrocarbons.


Visualisation of floading in a wire mesh.
