A radially outward flow turbine having a rotor (23) with nozzles (19) which extend from an inner inlet passage (16) to the rotor periphery with a substantially constant pressure drop per unit length of nozzle, with a first oder surface continuity along the surface of each nozzle and with a nozzle profile which allows two-phase flow without substantial lateral acceleration according to formula (I). The turbine is also illustrated with a second set of nozzles (29, 41) outwardly of the first set included in either the rotor or in a second contrarotating rotor (34). The rotor in either case vents steam to multiply steam turbine stages (32, 44) 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. |
