Abstract
Increasing the unit power of hydraulic turbomachines, as well as reducing their size, lead one to operate them on the verge of cavitation. It is then no more possible to think only of modifications in the machine performance, as many other phenomena take place long before this deterioration appears: noise, presence of bubbles, erosion, pressure fluctuations, etc. The article surveys the various phenomena encountered in pumps for various levels of suction pressure. Each is briefly described, with its implication on the machine. Industrial examples illustrate these phenomena and bring to light their importance. Lastly, the research tools used to study them and to overcome the present limitations are reviewed. Emphasis is made in particular on the possibility of predicting cavitation pockets either from numerical models of the flow or from experiments on actual models. Studies on erosion are also listed: mechanism, main parameters, measuring means, similitude laws for turbomachines.
