ABSTRACT:
A radially outward flow turbine having a rotor with nozzles which extend from an inner inlet passage to the rotor periphery with a substantially constant pressure drop per unit length of nozzle, with a first order surface continuity along the surface of each nozzle and with a nozzle profile which allows two-phase flow without substantial lateral acceleration according to the following formula: ##EQU1## The turbine is also illustrated with a second set of nozzles outwardly of the first set included in either the rotor or in a second contrarotating rotor. The rotor in either case vents steam to multiple steam turbine stages while the second set of nozzles receives saturated vapor. The steam turbine stage may be defined by either the first rotor and a stator or the first rotor and a contrarotating rotor.
