Abstract

PURPOSE: In the waterwheel casing for the hydraulic power plant, the sectional area of the water flow path at the winding end part of the casing is kept at 20 - 50% for the sectional area of the winding starting part, and the sectional area over these parts is varied smoothly, and the waterwheel efficiency is improved.
