Scaled Models for Underwater Acoustics and Geotechnics Applications
Abstract:The aim of this study was to investigate whether scaled models are useful tools for the validation of numerical codes for sound propagation in the ocean and to discuss the advantages and drawbacks of this approach for the modellers. Comparisons were made between numerical results obtained with the SAFARI code and experimental data obtained in a water tank. Preliminary results were very promising and showed that scaled models are useful tools for underwater acoustics applications and especially for the case of propagation loss estimation. Another example showing the relevance of scaled models for sea bottom characterization is described. Some results obtained in the laboratory are presented and their usefulness prior to full-scale investigations is investigated. Among the main advantages of the use of scaled models it can be mentioned the repetitiveness of the measurements and the precise determination of all the physical parameters during the experiments, which is never the case during sea trials. Finally, the applicability and also the flexibility of this approach to describe very complex situations is discussed.
