The calculation of aerator to prevent cavitation on spillways and chutes

Abstract

    The calculation and arrangement of aerators of spillways to prevent cavitation are very necessary in the spillway with high velocity. Follow theory and pratice of arrangement of aerators to avoid cavitation on the spillway and the chute, calculation and designing processes of cavitation were showed in this paper. We see that, the results obtained from calculation in CuaDat spillway is in accordance with the results of experiment modelling. The mothod is proposed to be appied widely to spillways.
