Abstract:
A process employing a rotary axial turbine having rotor blades, and a nozzle, that includesa) providing a working fluid expansible from a characteristic supercritical region into the wet region, b) expanding said fluid from said supercritical region into said wet region via said nozzle and turbine blades, c) and providing an output shaft driven by the turbine, d) the nozzle operated to produce condensation droplets, e) and collecting a substantial fraction of the said condensation droplets on the axial flow structure of the turbine, said structure including concave blade surfaces and a shroud extending about tips defined by the blades, the bulk of the liquid leaving the turbine rotor with a swirl path extending about and lengthwise of the turbine axis.
