Tutorial — 3D Flows in Axial Flow Turbines — Lesson 3

This lesson covers the design and analysis of axial flow turbines. It delves into the three-dimensionality of flow through these turbines, highlighting the non-uniformity of flow through the annulus space available to the turbines. The lesson also discusses the importance of factoring in variations from the lower radius to the outer radius, or from the root to the tip of the blade of a rotor, in the design and subsequent computations. It further explores different design theories that factor in the three-dimensionality of the flow and how they are used in the design and post-design analysis of turbines. The lesson concludes with a discussion on solving problems related to three-dimensional flow in axial flow turbines, using the theories discussed.
