Abstract

PURPOSE: Control of air-supply, when feeding air within a draft tube of a water wheel, after starting air-supply by initially setting the position of an air-supply opening at the center portion, by control of shifting the opening of the tube to an area with the lowest pressure corresponding to opening of a guide vane against water wheel load variation.
