Review of research on sail hydrodynamic noise and control technology

  • The sail is one of the most prominent contributors to the hydrodynamic noise of a submarine. This study seeks to analyze the mechanisms and characteristics of sail hydrodynamic noise, and summarize the characteristics and development trends of its control technology. First, the basic mechanisms and composition of sail hydrodynamic noise are summarized, as well as the research status of the direct radiation noise, secondary noise and cavity noise induced by flow-excitation of sails' opening. The research progress of sail noise control technology is then summarized, including fillet design, "thin foil" sail shape design, cavity noise control, etc. Finally, several aspects of further research on the control of sail hydrodynamic noise are proposed. This paper illustrates the basic mechanisms in the progress of sail hydrodynamic noise control technology. It can provide important reference value for researchers engaging in hydrodynamic noise and ship design.
