Abstract

This project is presented to meet Western Michigan University’s College of Engineering and Applied Sciences Senior Design requirements. With wind turbines becoming increasingly popular as a form of energy generation, the need to reduce the aerodynamic noise is needed. Most commercial wind farms use turbines with a NACA 0012 airfoil. Thus, that is the only profile shape considered in this research. Seven modifications were made to a NACA 0012 airfoil to reduce aerodynamic noise. The airfoils were designed in SolidWorks and 3D printed at the WMU College of Aviation. The airfoils were simulated in Ansys Fluent and experimentally tested in the anechoic wind tunnel in WMU’s Fluid Mechanics Laboratory. A National Instruments Data Acquisition System (DAQ) and MATLAB codes were used to collect acoustic signals from the airfoils. Ansys CFD Post was used to collect and process the experimental data. Recommendations are provided for future research in aerodynamic noise reduction.
