<P>PROBLEM TO BE SOLVED: To further improve efficiency of a rotary machine. <P>SOLUTION: The rotary machine M1 includes: a rotary body 12 rotating about an axis line P; and a flow passage 13 through which a working fluid W circulates toward a main radial direction. In the rotary machine M1, a curvature radius of a curve of at least one of corner parts 13r in a cross-section shape perpendicular to an extending direction of the flow passage 13 is gradually increased as proceeding toward an intermediate part 13c from an inlet 13a of the flow passage 13, while being gradually reduced as proceeding toward an outlet 13b from the intermediate part 13c of the flow passage 13. <P>COPYRIGHT: (C)2012,JPO&INPIT |
