Fluid flows parallel to the shaft axis. Highly efficient for handling high flow rates with relatively low pressure changes (e.g., jet engine compressors).
Fluid moves parallel to the shaft. Axial machines handle high mass flow rates with relatively low pressure changes per stage. Examples include jet engine compressors and steam turbines. turbomachines a guide to design selection and theory pdf
Choosing the right turbomachine depends on matching the machine’s characteristics to its application: Fluid flows parallel to the shaft axis
