Turbo-expander for isobutane working fluid

22. 3. 2021

The expander will be based on impulse axial single-stage turbine. Tests will be performed (apart from possible primary verification) at isobutane test rig at NTNU. Expected design parameters: inlet pressure in the range 600-1600 kPa, inlet temperature up to 150°C, outlet pressure 200 kPa, power output 25-50 kW.
