Starting the design process by testing on a small scale is often the best way to tackle issues affecting large objects, like a ship. Detailed in COMSOL News 2013, researchers at INSEAN, The Italian Ship Model Basin, used small-scale testing and then simulation to analyze the effect of placing a sonar system within the bulbous bow at the hull of a ship. Using a small-scale model of a bulbous bow, the researchers at INSEAN performed fluid-structure interaction experiments, and subsequently created a simulation model to validate an experimental-numerical procedure at the model size. Afterwards, they created a full-scale model within COMSOL Multiphysics using an in-house program as input to account for the size scaling. Interfacing LiveLink™ products were also used to manage external CAD data and integrate COMSOL Multiphysics with the in-house program. The full-scale model analyzed the structural, fluid, and acoustic properties that would impact the sonar system housed in the bulbous bow, as well as provided a framework for future researchers to expand upon.
