The booklet offers a close method of the physics, fluid dynamics, modeling, experimentation and numerical simulation of cavitation phenomena, with certain emphasis on cavitation-induced instabilities and their implications at the layout and operation of excessive functionality turbopumps and hydraulic generators. the 1st half covers the basics (nucleation, dynamics, thermodynamic results, erosion) and different types of cavitation (attached cavitation, cloud cavitation, supercavitation, vortex cavitation) correct to hydraulic turbomachinery, illustrates glossy experimental concepts for the characterization, visualization and research of cavitating flows, and introduces the most elements of the hydrodynamic layout and function of axial inducers, centrifugal turbopumps and hydo-turbines. the second one half specializes in the theoretical modeling, experimental research, and sensible keep watch over of cavitation-induced fluid-dynamic and rotordynamic instabilities of hydraulic turbomachinery, with exact emphasis on cavitating turbopumps (cavitation surge, rotating cavitation, greater order cavitation surge, rotordynamic whirl forces). eventually, the 3rd a part of the e-book illustrates the choice ways for the simulation of cavitating flows, with  emphasis on either modeling and numerical points. Examples of purposes to the simulation of unsteady cavitation in inner flows via hydraulic equipment are illustrated in detail.
