The book "Fluid Dynamics of Cavitation and Cavitating Turbopumps" offers a comprehensive analysis of the fluid dynamics of cavitation, particularly in the context of high-performance turbopumps. It highlights the challenges that cavitation poses to the performance and lifespan of these pumps and examines the conditions that can lead to dangerous fluid dynamic instabilities. The first part of the book addresses fundamental aspects of cavitation, including nucleation, bubble dynamics, and thermodynamic effects. Additionally, various types of cavitating flows, such as attached cavitation and vortex cavitation, are described in detail. The second part focuses on the hydrodynamics and instabilities of cavitating turbopumps, while the third part presents alternative approaches to modeling and engineering simulation of cavitating flows. This technical book is aimed at professionals and students who wish to develop a deeper understanding of cavitation and its effects on turbopumps.
