Abstract
This invention relates to a channel for supplying water to a vertical-axis Kaplan water turbine, wherein the vertical side walls thereof are oriented in convergent manner in order that, at turbine level, they join an end face of rounded form, of which the radius of curvature is slightly greater than the radius of the guide blades located above the turbine and the sleeve of the turbine shaft and/or an inclined fixed wall downstream of the turbine are provided, for preventing the development of suction eddies downstream of the sleeve of the turbine shaft.
