This work examines the complex phenomenon of secondary flows within turbomachines, a critical area for understanding and improving the efficiency of these systems. Secondary flows represent deviations from the intended primary flow path, originating from boundary layer interactions with blade cascades and end walls. These flows are a significant source of aerodynamic losses, often contributing between 30% and 50% of the total aerodynamic losses in components like blade or stator rows, directly impacting the performance of axial flow turbines used in aircraft and power generation.

The text details the formation of these intricate flow patterns, including the generation of longitudinal vortices and their role in overall loss mechanisms. It provides insights into the theoretical underpinnings and practical implications of secondary flow phenomena. Understanding the principles outlined here offers a foundation for developing strategies to mitigate these losses, thereby enhancing turbomachinery efficiency and operational effectiveness.
