Model Study to Locate Aerators in Tunnel Spillways

by Gabriel Echavez, UNAM, Mexico City, Mexico,

Document Type: Proceeding Paper

Part of: Hydraulic Engineering


A model study to locate, in an optimum way, aerators in tunnel spillways is presented. A Froude half model, scale 1:30, was used. The flow geometry, the air discharge sucked by the aerators and some considerations about the air concentration at a critical point are given.
