WitrynaAccording to Brümmer (2012), the tip speed commonly ranges between 20 and 40 m/s for unsynchronized twin-screw expanders and between 60 and 120 m/s for synchronized ones. Much lower values are typically reached for piston and scroll machines. The expander displacement is related to the rotor diameter.
