Flow noise has been investigated by the collaborative US-NL project Mechanisms and Prediction of Surface Ship Radiated Flow Noise. The paper will discuss the test set-up and results of the model scale experiments which were made in a (highly reverberant) towing tank. A special silent towing carriage was developed to reduce the background noise, while an acoustic antenna was used to measure the noise due to the breaking bow waves. The pressure fluctuations due to the turbulent boundary layer were measured at several hull locations.
