3D Axial Flow Compressors

This course covers the principles, dynamics, design, and analysis of three-dimensional flows in axial flow compressors. It starts with an introduction to the aerodynamics of turbomachinery and the evolution of two-dimensional flows into three-dimensional flows. The course then delves into the rotational nature of the blades, the concept of passage vortex, and the repercussions of three-dimensionality on the design and analysis of turbomachinery. It further explores the mathematical forms used to capture these flow features, the concept of radial equilibrium of forces, and the free vortex law. The course also discusses the principles of blade design, the impact of blade geometry, aspect ratio, and operating conditions on the design process. Lastly, it covers the application of various flow theories in the design and analysis of axial flow compressors.
