While the title by Hany Moustapha and co-authors is a seminal work in turbomachinery originally published in 2003 , its principles remain the gold standard for modern engineers. In 2021, research in the field—including studies from MDPI Energies —continues to build upon Moustapha's foundational methods to compare axial and radial configurations for new applications like small-scale power generation and underwater vehicles.
Techniques for predicting how long a blade will last under extreme thermal and mechanical loads.
Fluid enters the rotor at a larger radius and flows inward toward the shaft axis. This results in a substantial reduction in radius as the fluid expands. 2. Comparative Performance and Applications
Moustapha's work is renowned for its focus on the "total design" of the turbine, moving beyond just aerodynamics to include:
Better stress distribution; Von Mises stress can be 10–30% of axial Higher at large scales due to easier air cooling Superior for small-scale applications like turbochargers 3. Key Design Themes from Moustapha et al.
