    Abstract: A hydraulic turbine includes a rotor with a runner, which is concentrically surrounded by a stator, whereby the runner comprises a plurality of runner blades arranged and distributed in a ring around a rotor axis, and each runner blade extends between a runner crown and a runner band; whereby the stator comprises a plurality of guide vanes arranged and distributed in a ring around the rotor axis, and each guide vane extends between an upper stator ring and a lower stator ring; and whereby a predetermined clearance is provided at least between the runner band and the lower stator ring. A substantial reduction of pressure pulsations in the vane-less gap between said runner blades of said runner is achieved by substantially increasing said predetermined clearance.

    Abstract: A vane body of a guide vane includes a leading edge, and a trailing edge which is located closer to a runner than the leading edge, when located radially outside the runner. A projection extending in a direction from the trailing edge toward the leading edge is provided on an internal-diameter side blade face of the vane body, at least in any one of one side area of the internal-diameter side blade face and the other side area thereof in an axial direction of a guide vane rotation shaft, the internal-diameter side blade face being disposed on a side of the runner. The projection has a projection rear end of an arcuate shape, which projection rear end is formed to extend along a rotation trajectory which is drawn by the trailing edge when the vane body is rotated about the guide vane rotation shaft.

    Abstract: Said hydraulic turbine includes a wheel which is made to rotate about a rotational axis (X2) by a main water stream (F1) going from a penstock to a suction tube along a flow path that passes through the wheel. Said turbine also includes first means that are placed outside the flow path of the main water stream (F1) and enable the mixing of a secondary water stream (F2), taken from the flow path and located upstream from the wheel, and an oxygen-containing gas (A2). Said turbine also includes second means for injection, downstream from the wheel of the turbine, a water/gas mixture (F3) produced in the first means.

    Abstract: A turbine for extracting kinetic energy from a fluid includes a runner, a turbine-inlet having an entrance and an exit that is adjacent the turbine's runner, and a turbine-outlet having an entrance that is adjacent the runner and an exit. The runner extracts kinetic energy from fluid flowing through the turbine; the turbine inlet directs flowing fluid into the runner; and the turbine-outlet directs flowing fluid away from the runner. When fluid flows through the turbine, the fluid flowing through the turbine-inlet toward the runner flows around and adjacent the fluid flowing through the turbine-outlet away from the runner.

    Abstract: A hydraulic machine according to an embodiment includes an inlet section into which water flowing from an upper pond flows, a runner configured to be rotated by water flowing out from the inlet section, an outlet section configured to flow out water flowing out from the runner to a lower stream, and a micro-nano bubble generator configured to generate water containing micro-nano bubbles. The micro-nano bubble generator supplies the water containing micro-nano bubbles to water flowing inside the hydraulic machine from a portion between the inlet section and the outlet section of the hydraulic machine.

    Abstract: A hydraulic machine according to embodiments described herein includes a channel defining member, a plurality of guide vanes, and a runner. The channel defining member defines a channel. Each of the guide vanes can turn about a turning axis. The runner is provided on an inner peripheral side of the guide vanes. The guide vane has a pair of edges facing the channel defining member. A disc member is provided to at least one of the edges of the guide vane. The disc member is buried in the channel defining member and includes a central axis which is the turning axis. The disc member overlaps with at least one of an upstream end of a downstream end of the guide vane when viewed from a direction along the turning axis.
