Axial and Radial Turbine Design
This course will provide both design and application engineers with a deep understanding of turbine performance. Throughout the course, emphasis is placed on the basic flow physics as reflected in both axial and radial turbine performance. Techniques by which a design can be optimized for new applications are emphasized, and the complete process for producing new designs or developing new components for existing machines is described, from the beginning to the final detailed design. Throughout the course, the effective use of modern computer systems, CFD, and FEA stress analysis codes is emphasized.
Lectures will cover the characteristics, design, and performance of axial, mixed, and radial flow turbines. Ancillary components such as exhaust diffusers are also discussed. A section of the course is devoted to turbine life, the factors which limit life, and the techniques to estimate it. Turbine testing techniques are described, with emphasis on the data which can be gathered and the means to process it effectively, and utilize test data in subsequent turbine development. A copy of the text, Axial and Radial Turbines, will be issued to each participant.
Participants earn 2.7 Continuing Education Units (CEUs).
What You Will Learn
- Develop an understanding of design and operational principles of all types of turbines.
- Understand how turbine designs may be optimized within given constraints, and the role of experimental turbine stage testing in this process.
- Become aware of the design features and operational factors which limit turbine life, and how that life may be estimated.
