What is the impact of blade skew and skew angle optimization on airflow and noise?

Blade skew, the angular displacement of blades relative to the rotational axis, plays a critical role in balancing airflow directionality against noise generation. Carefully optimized skew angles can direct airflow more precisely through dense radiators or filters, reducing turbulence-induced noise. According to empirical research published in the Journal of Acoustic Engineering, implementing a skew angle of approximately 15 degrees can significantly decrease cavitation and vortex shedding, phenomena responsible for high-frequency noise.
