An introduction to cavitation in inducers and turbopumps -- Experimental methods for the study of hydrodynamic cavitation -- An introduction to flow-induced instabilities in rocket engine inducers and turbopumps -- 3-D simulation of cavitation instabilities -- Rotordynamics of turbopumps and hydroturbines -- On the preliminary design and performance prediction of centrifugal turbopumps -- Numerical simulation of cavitating flows with different cavitation and turbulence models -- Numerical simulation of cavitating flows in complex geometries -- From cavitating to boiling flows.

The book provides a detailed approach to the physics, fluid dynamics, modeling, experimentation and numerical simulation of cavitation phenomena, with special emphasis on cavitation-induced instabilities and their implications on the design and operation of high performance turbopumps and hydraulic turbines. The first part covers the fundamentals (nucleation, dynamics, thermodynamic effects, erosion) and forms of cavitation (attached cavitation, cloud cavitation, supercavitation, vortex cavitation) relevant to hydraulic turbomachinery, illustrates modern experimental techniques for the characterization, visualization and analysis of cavitating flows, and introduces the main aspects of the hydrodynamic design and performance of axial inducers, centrifugal turbopumps and hydo-turbines. The second part focuses on the theoretical modeling, experimental analysis, and practical control of cavitation-induced fluid-dynamic and rotordynamic instabilities of hydraulic turbomachinery, with special emphasis on cavitating turbopumps (cavitation surge, rotating cavitation, higher order cavitation surge, rotordynamic whirl forces). Finally, the third part of the book illustrates the alternative approaches for the simulation of cavitating flows, with  emphasis on both modeling and numerical aspects. Examples of applications to the simulation of unsteady cavitation in internal flows through hydraulic machinery are illustrated in detail..
