Turbopumps
This book covers most of the subjects that are requested by engineers, those who are directly involved in design and manufacturing the pumps to those who operate the pumps in industrial units. The authors have worked for many years teaching the subject, conducting research, and implementing pump and pump station designs in different academic institutions, industrial sectors, and consulting firms. Based on this extensive background, the material of the book is arranged to cover the most important topics, from basic theories to practical applications. The book is divided into two major Parts. In Part I, Turbopumps, the basic information about pumps classification, definitions, principal of operation, and construction elements are presented. In Part II, Pumping Systems, the important parameters in pump operation, selection, pumping systems, and pump stations are discussed in details.
Fluid dynamics of cavitation and cavitating turbopumps
The book focuses on the fluid dynamics of cavitation with special reference to high power density turbopumps, where it represents the major source of performance and life degradation and often generates the conditions for the onset of dangerous fluid dynamic instabilities. To this purpose the first part of the book covers the more fundamental aspects of cavitation (nucleation, bubble dynamics, thermodynamic effects, cavitation erosion, stability of parallel bubbly flows) and the main kinds of cavitating flows (attached cavitation, cloud cavitation, supercavitation, ventilated supercavities, vortex cavitation, shear cavitation). The second part focuses on the hydrodynamics and instabilities of cavitating turbopumps (cavitation surge, rotating cavitation, higher order cavitation surge, rotordynamic whirl forces). Finally, the third part illustrates the alternative approaches for modeling and engineering simulation of cavitating flows.
