Axial turbines are characterized by their axial flow direction, where the fluid flows parallel to the turbine's rotational axis. In an axial turbine, the fluid flows through a series of blades, which are attached to a central hub. As the fluid flows over the blades, it transfers its energy to the blades, causing the turbine to rotate. Axial turbines are commonly used in applications such as steam turbines, gas turbines, and wind turbines.
Radial turbines have several performance characteristics that make them suitable for various applications:
| Parameter | Axial Turbine | Radial Turbine | |-----------|---------------|----------------| | Specific speed | High (0.8–2.5) | Low (0.3–0.8) | | Max efficiency | Up to 92% | Up to 88% | | Number of stages | Multi-stage possible | Typically single-stage | | Manufacturing cost | Higher | Lower | Axial And Radial Turbines By Hany Moustapha.pdf
Turbines are devices that convert the kinetic energy of a fluid (liquid or gas) into mechanical energy, which can be used to generate power or perform work. The two main types of turbines are axial and radial turbines, classified based on the direction of fluid flow relative to the turbine axis. Axial turbines have a parallel flow direction, while radial turbines have a radial flow direction.
Turbines convert thermal and kinetic energy into mechanical work. Two primary configurations exist: axial flow and radial flow. This paper reviews their fundamental differences, design methodologies, and performance characteristics based on Hany Moustapha’s comprehensive text.

Turbine Aerodynamics: Axial and Radial Turbines by Hany Moustapha provides a comprehensive analysis of the fluid mechanics, thermodynamic principles, and design methodologies essential for high-efficiency turbomachinery. The literature outlines that while axial turbines are optimized for high mass flow in power generation, radial turbines excel in compact, high-pressure-ratio applications like turbochargers.
