In this report some further considerations concerning towing tank wall pressure fluctuations (WPF) data analysis are presented. The main objective of the present work is to investigate the capabilities and the limitations of available semi-empirical models for the representation of WPF power spectral density (PSD) and cross spectral density (CSD) by comparison with experimental data acquired during the FLAME towing tank test campaign. The performed analysis reveals that when suitable values of the free model parameters are chosen it is possible to derive analytical formulations for the single point pressure spectrum and for its spatial behaviour. These results are fundamental to provide the input for the structural analysis.

Abstract
In this report some further considerations concerning towing tank wall pressure fluctuations (WPF) data analysis are presented. The main objective of the present work is to investigate the capabilities and the limitations of available semi-empirical models for the representation of WPF power spectral density (PSD) and cross spectral density (CSD) by comparison with experimental data acquired during the FLAME towing tank test campaign. The performed analysis reveals that when suitable values of the free model parameters are chosen it is possible to derive analytical formulations for the single point pressure spectrum and for its spatial behaviour. These results are fundamental to provide the input for the structural analysis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
