A STUDY ON THE VORTEX FLOW NEAR POWER HOUSE INTAKE STRUCTURE OF LONGTAN HYDROELECTRIC PROJECT

摘要

In connection with the model test for flow condition of Longtan Hydroelectric Project (LHP) power house intake, this paper discusses the cause of vortex flow near the intake , its affecting factors and measures to eliminate it. Some modifications to the existing empirical formula and extension to its scope of calculation in order to replace model test with an empirical formula are suggested to provide basis for the design of intake .
