Noise generation was significantly reduced by 28% after modifying axial fan blade geometry, improving efficiency and comfort.
The study compares sound levels from original and modified fan blades to identify effective noise mitigation techniques.
Using a seven-blade axial fan case study, effects of boundary layer modifications were systematically analyzed for noise reduction.
Findings imply that enhancing fan design could extend component lifespan, suggesting broader applications across various industries.
