Axial and Radial Turbines
While Hany Moustapha’s seminal textbook, , was originally published in 2003 with Concepts NREC, his work remains a foundational technical reference for modern turbine design and performance prediction. Moustapha, a Senior Fellow at Pratt & Whitney Canada, is globally recognized for his contributions to turbine aerodynamics, emphasizing the integration of advanced three-dimensional computational tools with classical design principles.

Chapter 1: Fundamentals of Turbine Operation
Turbines are devices that convert the energy of a fluid (liquid or gas) into rotational energy, which can be used to generate power. The two primary types of turbines are axial and radial, classified based on the direction of fluid flow relative to the rotor. Axial and Radial Turbines While Hany Moustapha’s seminal
pragmatic engineering guide
The work “Axial and Radial Turbines” by Hany Moustapha (2021) is not merely a collection of formulas and diagrams. It is a that bridges classical theory (Smith chart, Balje diagrams) with modern computational design. Whether you are a graduate student selecting a turbine for a rocket turbopump or a senior engineer optimizing a turbocharger for a low-carbon engine, the axial vs. radial decision framework presented by Moustapha is invaluable. Axial velocity ((V_a)) is constant across the stage
This equation highlights a fundamental design difference: In axial turbines, $U$ is constant across the stage (ignoring radial variations), simplifying the energy transfer analysis. In radial turbines, the change in radius from inlet to outlet provides a significant contribution to the work output via the $U_1 C_\theta 1$ term, allowing for high pressure drops across a single stage.
- Axial velocity ((V_a)) is constant across the stage (idealized).
- Work factor (\psi = \Delta V_\theta / U) is typically 1.5–2.0.
