Experimental Investation of Flow Aeration on Chute Spillway The study focused on derivation of relationships by using a wide range of geometries and flow conditions to estimate the coefficient of air entrainment. In outlet conduits and tunnel spillways, hh velocity flows and pressure reduction provide situation favorable for cavitations erosion. Spillways are one of the most important structures which are responsible to carry out. Experiments were performed on different hydraulic models including of Azad. So, with the flow velocity of 30 m sec-1, 5-7% air concentration would be enough to. In IAHR Hydraulic Structures Desning Manual No.
