Abstract:
A runner vane of an axial hydraulic machine according to embodiments described herein includes a center-side vane part provided on a radial center side and defined by a center-side camber line, and a boss-side vane part provided at a side edge on a side of a runner boss and defined by a boss-side camber line. As determined by the flow direction of a turbine, a curvature of an upstream side portion of the boss-side camber line is larger than a curvature of an upstream side portion of the center-side camber line. An upstream end of the boss-side vane part is positioned on a side of a rotation direction of a runner in comparison with an upstream end of the center-side vane part when viewed toward a downstream side along a rotation axis line of the runner.
