This book provides engineers and scientists with practical fundamentals for turbomachinery design. It presents a detailed analysis of existing procedures for the analysis of rotor and structure dynamics, while keeping mathematical equations to a minimum. Specific terminologies are used for rotors and structures, respectively, allowing the readers to clearly distinguish between the two. Further, the book describes the essential concepts needed to understand rotor failure modes due to lateral and torsional oscillations. It guides the reader from simple single-degree-of-freedom models to the most complex multi-degree-of-freedom systems, and provides useful information concerning steel pedestal stiffness degradation and other structural issues. Fluid-film bearing types and their dynamical behavior are extensively covered and discussed in the context of various turbomachinery applications. The book also discusses shaft alignment and rotor balancing from a practical point of view, providing readers with essential information to help them solve practical problems. As the main body of the book focuses on the diagnostics and description of case studies addressing the most pressing practical issues, together with their successful solutions, it offers a valuable reference guide, helping field engineers manage day-to-day issues with turbomachinery.

Raj Subbiah received his undergraduate and master's degrees in mechanical engineering from the University of Madras, India and the Indian Institute of Technology, New Delhi, respectively. He received his Ph.D. from Concordia University, Montreal, Canada. His work involves the design, analysis and servicing of turbine-generators applied in fossil, nuclear and small industrial turbines. He has published more than 100 papers in respected international journals, symposia proceedings and internal company reports. He has delivered several invited lectures and conducted workshops on turbo-machinery vibration for both academic institutions and industries at home and abroad. Although his specialization is rotor dynamics, he also worked on other areas such as structural dynamics and fracture mechanics extensively for more than 38 years. He is a member of ASME and has been part of the ISO committees on vibration for over 25 years. He led the development of torsional vibration and pedestal degradation standards. He is currently a senior advisory head in rotor dynamics works at Siemens Energy, Inc. Jeremy Eli Littleton received his undergraduate and master's degrees in mechanical engineering from the University of Pittsburgh and the University of Florida, respectively. He has worked in the turbine-generator field balancing and rotor dynamics for 18 years since then. During this time, he has been active in various root cause analyses involving vibration - in small industrial units as well as large nuclear units. For the past seven years, he has also been the subject matter expert in field balancing and vibration analysis for Siemens Energy, Inc., and has thus become very familiar with a wide range of common and unique rotor issues.
