| Abstract: | The results of experimental study of flow pattern in the end clearance of guide-vane of water-turbine by means of visualization are presented in this paper. The pressure distribution in the end clearance of hollow guide-vane and solid guide-vane is obtained by surveying the pressure in the end clearance under the conditions of clean water and muddy water. By comparing and analyzing, one of the measures to reduce the wear and cavitation damage of the end clearance of guide-vane is advanced. |
