Abstract

This paper presents the results of an experimental investigation designed to predict the formation of weak, free-surface vortices at vertical intakes with a headrace channel. A weak vortex is defined as a coherent, persistent dye core into the intake, the vortex classification to be avoided at pump and turbine intakes. Primary application is in the design of vertically arranged intakes for hydropower facilities. The experiments emphasize approach flow angle, intake submergence, intake velocity, and the length/width ratio of the headrace.
