Radial Turbines

This course covers the comprehensive understanding of radial flow turbines, a significant type of turbomachinery. It starts with the fundamentals of turbomachinery aerodynamics, focusing on the working principles, applications, and different types of radial flow turbines. The course delves into the thermodynamics and aerodynamics of these turbines, including the calculation of losses. It also provides a historical perspective of radial flow turbines, their evolution, and modern versions. The course further discusses the blade shapes and geometries, the flow analysis, and the governing equations. It also covers the efficiency and performance parameters, including the total-to-static efficiency and work output. The course concludes with the design characteristics of radial flow turbines, their advantages over axial flow turbines, and the use of Computational Fluid Dynamics (CFD) in their design process. For instance, the course uses the example of a micro gas turbine to illustrate the application of radial flow turbines in real-world scenarios.
