Moustapha’s analysis demonstrates that peak isentropic efficiency is achieved at . However, physical engineering demands a trade-off: designing for ultimate efficiency can increase engine length, weight, and stage count. Degree of Reaction (
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. Axial and radial turbines are two common types of turbines used in various industries. Axial turbines have a rotational axis parallel to the flow direction, while radial turbines have a rotational axis perpendicular to the flow direction. Both types of turbines have their advantages and disadvantages, which will be discussed in this article. axial and radial turbines by hany moustaphapdf 2021

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. The fundamental equation governing the transfer of energy
