Flow Direction: Inward, perpendicular to the axis.
Moustapha uses these cases to validate his design charts.
Radial (or centrifugal) turbines have flow entering near the periphery, moving radially inward, and exiting axially. The main components:
Axial turbines are the undisputed kings of high-power applications. If you look at the engine of a commercial airliner or a massive steam power plant, you are looking at an axial turbine.
"Axial and Radial Turbines" (2021) by Hany Moustapha provides a comprehensive, engineering-focused overview of the two primary categories of turbomachines used for power generation, propulsion, and energy recovery.
The document systematically contrasts axial turbines (where flow remains parallel to the axis of rotation) and radial (centripetal) turbines (where flow enters radially outward and moves inward toward the center). Key areas covered likely include:
While the specific publisher is not listed, Hany Moustapha is a recognized authority in turbomachinery, and the 2021 PDF is likely intended as a technical reference for graduate students, mechanical/aerospace engineers, and researchers in turbomachinery design.

Axial and Radial Turbines: A Comprehensive Review
Introduction
Turbines are a crucial component in various industrial applications, including power generation, aerospace, and chemical processing. They are used to convert the kinetic energy of a fluid into mechanical energy, which can then be used to drive a generator, pump, or other machine. There are several types of turbines, but this blog post will focus on axial and radial turbines, two of the most common types. In this article, we will review the fundamentals, design considerations, and applications of axial and radial turbines, with a focus on the latest developments and research in the field.
Axial Turbines
Axial turbines, also known as axial flow turbines, are a type of turbine where the fluid flows parallel to the axis of rotation. In an axial turbine, the fluid enters the turbine at the inlet, flows through the blades, and exits at the outlet, with the direction of flow remaining parallel to the axis of rotation. Axial turbines are widely used in applications such as steam turbines, gas turbines, and hydro turbines.
Design Considerations for Axial Turbines
The design of axial turbines involves several key considerations, including:
Radial Turbines
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.
Design Considerations for Radial Turbines
The design of radial turbines involves several key considerations, including:
Comparison of Axial and Radial Turbines
Axial and radial turbines have several differences in terms of design, performance, and application. Some of the key differences include:
Applications of Axial and Radial Turbines Flow Direction: Inward, perpendicular to the axis
Axial and radial turbines have a wide range of applications in various industries, including:
Latest Developments and Research
The field of axial and radial turbines is constantly evolving, with ongoing research and development aimed at improving efficiency, reducing costs, and increasing reliability. Some of the latest developments and research in the field include:
Conclusion
In conclusion, axial and radial turbines are two of the most common types of turbines used in various industrial applications. Understanding the fundamentals, design considerations, and applications of these turbines is crucial for engineers and researchers working in the field. This article has provided a comprehensive review of axial and radial turbines, including the latest developments and research in the field. As the demand for efficient and reliable turbines continues to grow, ongoing research and development will play a critical role in shaping the future of axial and radial turbines.

In both gas turbine engines and turbochargers, the turbine extracts energy from a hot, high-velocity gas stream and converts it into mechanical shaft work (to drive a compressor or fan). The two primary architectures are Axial and Radial (often called centripetal).
Moustapha emphasizes that loss prediction is still semi-empirical, and designers must validate with experimental data.
To characterize performance irrespective of physical size, engineers utilize dimensionless parameters: Radial (or centrifugal) turbines have flow entering near
