May Published 1975 Physics Abstract : This report contains a comprehensive compilation of test data and analytical techniques for predicting the behavior of vehicles during water entry and during the cavity-running phase. Web1 de mar. de 2024 · A chute aerator is a device that entrains air into water and protects against cavitation erosion. The state of the jet cavity determines the aerator efficiency under different flow conditions. In the case of a low Froude number and low velocity, backwater is generated in the jet cavity. In severe cases, this backwater blocks the air intake holes …
