Abstract
To localize cavitation noise using the beam forming method, sensors are mounted above the propeller on the hull surface of a model-scale ship. Beam forming results are highly dependent on the number and arrangement of sensors; thus, an array with a large number of sensors for a wide range will have good performance. However, it is difficult for such a system to be applied to a model scale, or to a full-scale ship in practical applications. A model-scale experiment was thus conducted at the cavitation tunnel of KRISO using various on-board sensor arrangements. The performance of each arrangement was verified from the experiment using the reference noise source, and it was confirmed that the location of the noise source could be estimated. Additionally, a feasibility study was carried out for a model ship with a single screw propeller, and it was confirmed that the location of the cavitation noise at the 12 o’clock position of the propeller was well represented.
