Abstract

In this paper, a prediction method of hydrofoil broadband noise is developed based on large eddy simulation (LES) methods and Ffowcs Williams- Hawkings (FW-H) equations. The broadband noise of an airfoil is calculated and the comparison of computed and measured sound pressure spectra shows good agreement over approximately a decade of frequency. The broadband noise of five different hydrofoils are calculated and presented in this paper. The relationship between the broadband noise of hydrofoils and the hydrofoil thickness and camber distributions are discussed. An optimized hydrofoil is presented in this paper for which the broadband noise is about 4 dB lower than NACA-66mod foil.
