About this document

Axial Fan Noise Reduction with Airfoils by Bhua Bilei is a document available to read on EtoBox.

This document summarizes research into using multi-element airfoils on axial fan blades to reduce fan noise. Axial fans are a major source of noise, and reducing fan tip speed is an effective way to lower noise, but it also reduces aerodynamic performance. The researchers designed a multi-element airfoil with two elements to increase lift at low Reynolds numbers, allowing lower fan tip speeds while maintaining airflow. Their airfoil design increased lift by 132% compared to a single-element airfoil, more th
