PROBLEM TO BE SOLVED: To provide a two-phase flow turbine nozzle capable of improving performance of a two-phase flow turbine, a two-phase flow turbine having improved performance, and refrigeration cycle.;SOLUTION: A two-phase flow turbine nozzle provided in a two-phase flow turbine driven by a gas-liquid two-phase flow of fluid includes a plurality of stator vanes arranged in a circumferential direction so as to form a flow passage therebetween. The outlet opening of the flow passage has a shape in which a width in a radial direction is longer than a width in the circumferential direction.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2020,JPO&INPIT
