Cavitation Instabilities and Rotordynamic Effects in by Luca d'Agostino,Maria Vittoria Salvetti PDF

The booklet offers a close method of the physics, fluid dynamics, modeling, experimentation and numerical simulation of cavitation phenomena, with precise 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 sorts of cavitation (attached cavitation, cloud cavitation, supercavitation, vortex cavitation) proper to hydraulic turbomachinery, illustrates sleek experimental innovations for the characterization, visualization and research of cavitating flows, and introduces the most features of the hydrodynamic layout and function of axial inducers, centrifugal turbopumps and hydo-turbines. the second one half makes a speciality of the theoretical modeling, experimental research, and functional keep an eye on of cavitation-induced fluid-dynamic and rotordynamic instabilities of hydraulic turbomachinery, with certain emphasis on cavitating turbopumps (cavitation surge, rotating cavitation, larger order cavitation surge, rotordynamic whirl forces). ultimately, the 3rd a part of the ebook illustrates the choice methods for the simulation of cavitating flows, with  emphasis on either modeling and numerical features. Examples of purposes to the simulation of unsteady cavitation in inner flows via hydraulic equipment are illustrated in detail.
