Abstract: Cavitation arising in hydraulic machines is an important problem which now is becoming more important because of the large diffusion of pumped hydroelectric storage plants, with the presence of pumps and turbines. With reference to a pump the presence of cavitation can be experimentally detected through the lowering of the performance of the pump. But the presence of cavitation can be detected without hydraulic measurements too. Some experiments have been carried out in Naples in order to test the acoustic method of detecting cavitation. The main results obtained are described in this paper.
