dc.description.abstractBladeless fans offer quieter operation and improved efficiency, but noise reduction at higher speeds remains challenging. This study evaluates a modified bladeless fan design with a wavy ledge to enhance noise reduction and aerodynamic performance. Experimental tests showed a reduction in sound pressure levels (SPL) by 1.67 dBA to 3.69 dBA, along with an increase in maximum outlet velocity from 14.3 m/s to 16.5 m/s, compared to conventional blades. The wavy ledged design provides an effective noise reduction solution, ideal for noise-sensitive environments. Future research should focus on real-world testing and further optimization of blade geometry.
