Axial And Radial Turbines By Hany Moustaphapdf High Quality ((link)) Jun 2026

In a radial turbine, the working fluid flows (radial inflow) and then turns to exit axially.

This equation clearly explains the performance differences between the two architectures. In an axial turbine, the blade speed at the inlet (U₂) and exit (U₃) are approximately equal, so the work comes almost entirely from a change in the fluid's tangential velocity ( Cw ). In contrast, for a radial turbine, the inlet blade speed (U₂) is significantly than the exit blade speed (U₃) because the flow moves to a smaller radius. This creates a larger change in angular momentum, allowing a radial turbine to extract more work per stage than an axial one of the same size. axial and radial turbines by hany moustaphapdf high quality
