Validate your RPM using his centrifugal stress equation for radial turbines: $\sigma = \rho \omega^2 R_mean^2$. If your number exceeds his recommended limit for Nickel superalloys (approx. 600 MPa), your file has prevented a physical explosion.
The book starts with the fundamental physics of energy conversion, using velocity triangles to analyze how gas flows through a turbine stage. It then progresses to advanced concepts like secondary flows, tip leakage, and real-world loss mechanisms. It provides engineers with the methods to optimize blade profiles for maximum power extraction while minimizing losses.
Dr. Hany Moustapha's " Axial and Radial Turbines " is a highly respected, essential reference that has helped educate a generation of turbine engineers. Authored by four of the world's leading experts, its comprehensive scope and blend of fundamental theory with practical design insights make it an indispensable tool for students and professionals alike. For anyone seeking to master this challenging but vital field, this book remains a must-read. Axial And Radial Turbines By Hany Moustapha.pdf
Use radial turbines for small power outputs (<500 kW) and high pressure ratios. Switch to axial turbines for large mass flows and multi-stage compounding.
"Axial and Radial Turbines" by Hany Moustapha et al. serves as a foundational text for understanding the aerodynamic, structural, and cooling design complexities of turbine machinery. The work details the distinct applications of axial designs for high-mass flow and radial designs for smaller power requirements, while addressing critical aspects like blade life prediction and computational fluid dynamics.
