Turbomachinery Design and Performance

This course is designed to present an overview of turbomachinery. It Mechanical will begin by covering fundamenEngineering tals such as nomenclature and the classification of turbomachines. It Advanced Technology & Management Programs will then move on to various mathematical analysis techniques that allow turbomachine performance to be calculated. The course will conclude by looking at a number of specific types of turbomachines, such as turbines, pumps, fans, and blowers, and interpreting real-world performance data for the machines. The course will be very interactive in nature. Participants will be given example problems to work in class and then the solutions to these problems will be used to illustrate and supplement the instruction.

Kevin Whitaker is an Associate Professor of Aerospace Engineering and Mechanics at the University of Alabama. He regularly teaches graduate and undergraduate courses on all aspects of aerodynamics and propulsion. His research interests have led him to work with the NASA on numerous occasions, most recently involving the performance analysis of the Space Shuttle Main Engine. Dr. Whitaker is also a co-principal investigator on a national effort to reform science, mathematics, engineering and technology courses for future teachers. In this regard he is part of a team conducting workshops for other highereducation faculty. He also actively involved with pedagogical reforms taking place in engineering education. Dr. Whitaker holds a B.S. in Mechanical Engineering from General Motors Institute (now know as Kettering University) and a M.S. in Mechanical Engineering and a Ph.D. in Aerospace Engineering both from Texas A&M University. He is a member of ASME and a senior member of AIAA.

INTENDED AUDIENCE: This course is designed for engineers, technicians, or technical program managers who need to have a basic understanding of turbomachine design and analysis.

PREREQUISITES: Participants should have a basic understanding of fluid mechanics, algebra and trigonometry. Calculators are strongly recommended.
