Comparison of Measured and Predicted Airfoil Self-Noise with Application to Wind211 Turbine Noise Reduction

摘要

In the ongoing JOULE-III project Development of Design Tools for Reduced211u001eAerodynamic Noise Wind Turbines (DRAW), prediction codes for inflow-turbulence 211u001e(IT) noise and turbulent boundary layer trailing-edge (TE) noise, are developed 211u001eand validated. It is shown that the differences in IT noise radiation between 211u001eairfoils having a different shape, are correctly predicted. The first, 211u001epreliminary comparison made between predicted and measured TE noise spectra 211u001eyields satisfactory results.
