Book Description
Changing any one component in a set of multiply connected cavities, such as the compressor discharge seal, causes flow changes throughout the entire engine. T-70O engine test data and numerical simulations of the space shuttle main engine high-pressure fuel turbopump, the four stage T-56/501D turbine, and swirl brake dynamics are cited as examples. The needs for time-dependent optimization of turbine and compressor flow fields, for use of seals to enhance rotor stability, for predictive maintenance, and for a clean-sheet approach to engine design are concluded.

Book Description
A guide for mechanical engineers to identifying flow-induced noise and vibration sources within machinery that could cause catastrophic failure. Explains methods for computing frequencies for self-sustained oscillations, and presents formulae to calculate the acoustic resonant modes for ducts and cavities. Considers the general types of flow configurations that are known to produce self-sustained oscillations and includes a complete collection of models.

Book Description
Hydrodynamics of Pumps is a reference for pump experts and a textbook for advanced students. It examines the fluid dynamics of liquid turbomachines, particularly pumps, focusing 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, 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 - discussed in the three final chapters. The book is richly illustrated and includes many practical examples.
