The term turbomachinery refers to machines that transfer energy between a rotor and a fluid (gas or liquid). These machines, which include turbines, compressors, pumps, and fans, are used in power generation, aerospace, oil and gas, and various industrial processes.

This book provides a clear and accessible foundation for learning the principles of turbomachinery, related analytical approaches, and numerical methods, as well as their applications in fields including mechanical engineering, aerospace, energy systems, and industrial design.

The book is intended for students and early-career professionals with a basic understanding of fluid mechanics and thermodynamics and aims to prepare readers for more advanced study in the field. However, it is not just for academics. It helps build the technical knowledge needed to innovate, design, and optimize energy, fluid systems, and beyond.

Dr. Sohaib Obeid is currently a faculty member at the University of Bridgeport in Bridgeport, Connecticut, where he teaches thermodynamics, fluid mechanics, and turbomachinery at both undergraduate and postgraduate levels. He also delivers specialized training for industry professionals through short courses focused on thermodynamics and turbomachinery. Before his current position, Dr. Obeid served as a Lecturer in Fluid Mechanics and Thermo-Fluid Sciences at Rowan University (2021–2023) and the State University of New York at New Paltz (2018–2019). His academic and professional trajectory has been shaped by a strong foundation in turbomachinery design, having worked in the power generation industry on projects involving large steam turbines, gas turbines (both large and small), hydroelectric turbines, and centrifugal pumps. His early career emphasized conceptual and optimal design approaches to turbomachinery, after which he returned to academia to complete a Ph.D. in turbine aerodynamics, supported by the United States Air Force.

Dr. Obeid’s research is primarily focused on advancing the efficiency of turbomachinery through the development of three-dimensional aerodynamic design methods. In addition, he is active in the renewable energy sector, with a particular emphasis on small wind turbine systems. His work includes both computational simulations and experimental studies aimed at enhancing the performance and viability of renewable energy technologies.
