Axial And Radial Turbines By Hany Moustaphapdf 2021 [updated] Jun 2026
The literature surrounding Hany Moustapha's expertise emphasizes a modern approach to design, focusing on integrating computer-aided engineering with aerodynamic fundamentals. A. Comprehensive Design Methodologies
Turbines are devices that extract energy from a fluid flow (gas or steam) and convert it into mechanical work, usually driving a generator, compressor, or propeller.
Modern radial turbines, particularly in turbochargers, use Variable Geometry Turbine (VGT) technology to adjust nozzle angles, enhancing efficiency across a wider range of mass flow rates. 4.

For , the blade speed remains essentially constant from the inlet to the outlet of a given streamtube ( ) because the radius does not change ( axial and radial turbines by hany moustaphapdf 2021
Based on the 2021 perspective, Moustapha identifies several trajectories:
by Hany Moustapha provides a comprehensive, engineering-focused overview of the two primary categories of turbomachines used for power generation, propulsion, and energy recovery.
, remains a foundational reference for modern turbine design, with principles that continue to inform research in 2021. The work highlights that while axial turbines are ideal for high-mass flow, large-scale applications, radial inflow turbines offer superior efficiency in small-scale, lower-expansion scenarios.

The text covers the full spectrum of turbine design, from initial thermodynamic sizing to detailed aerodynamic analysis.
Radial turbines, also known as radial flow turbines, are a type of turbine where the fluid flows radially outward or inward from the axis of rotation. In a radial turbine, the fluid enters the turbine at the center, flows through the blades, and exits at the periphery, with the direction of flow changing from radial to axial. Radial turbines are widely used in applications such as centrifugal compressors, pumps, and turbines. including the blade design
Design and Off-Design Performance Improvement of a Radial-Inflow Turbine January 2021
The fundamental distinction between axial and radial turbines lies in the direction of the flow relative to the axis of rotation.
In , because the fluid travels parallel to the axis of rotation, the mean radius remains constant from inlet to exit ( ), meaning
The performance of axial turbines is characterized by their efficiency, power output, and flow coefficient. The efficiency of an axial turbine depends on various factors, including the blade design, angle of attack, and Reynolds number. Hany Moustapha's publication provides an in-depth analysis of the design and performance of axial turbines, including the effects of various design parameters on turbine efficiency.
