Calculation of Noise Emission Caused by the Flow of the Body with Cavity Using Integral Acoustic Analogy

The acoustic design stage plays an important role in the design of marine facilities. Currently, in addition to model tests, numerical modeling methods are also used in the design of ships. The designed vessels must comply with international noise emission standards. The level of emitted noise, in addition to mechanisms and propulsion systems, can also be influenced by the shape of the projected vessel. This report provides a calculation example of hydrodynamic and acoustic characteristics of the body with cavity using numerical modelling with the help of eddy-resolving approaches in the hydrodynamics task and acoustic analogy in the acoustics tasks.
