Hydrodynamics of Pumps

This book is about the fluid dynamics of liquid turbomachines, particularly pumps; and serves as a reference for pump experts and a textbook for advanced students exploring pumps and pump design. It focuses on special problems and design issues associated with the flow of liquid through a rotating machine. There are two characteristics of a liquid that lead to problems and cause a significantly different set of concerns than those in gas turbines. These are the potential for cavitation and the high density of liquids, which enhances the possibility of damaging, unsteady flows and forces. The book begins with an introduction to the subject, including cavitation, unsteady flows, and turbomachinery as well as basic pump design and performance principles. Chapter topics include flow features, cavitation parameters and inception, bubble dynamics, cavitation effects on pump performance, and unsteady flows and vibration in pumps. The book is richly illustrated and includes many practical examples.
