(US5720799-A)      The multistage two-phase turbine (10) has stages which receive fluids comprising a mixt. of gas and liq. Each stage has inlet and outlet nozzles to accelerate the fluids which form two-phase jets. A rotating separator structure provides gas and liq. streams (12,15) at each stage.    The turbine extracts kinetic energy from the liq. streams into shaft power to drive a generator (11) and the sepd. liq. is removed and transferred to a sec. outlet.    ADVANTAGE -   Gives improved turbine operation and waste heat usage esp. for reducing pressure from geothermal wells, using steam and re-injecting brine also for oil and gas prodn. from high pressure wells.
