Turbulent-induced Noise of 2-dimensional Sonar Dome Shaped Structure Choi, Yo-Seb; Hong, Suk-Yoon; Song, Jee-Hun; Kwon, Hyun-Wung; Choi, Woen-Sug; Jung, Chul-Min;
The latest research has shown that the turbulence-induced noise is important in total characteristics of flow noise. Also, turbulence-induced noise have a significant influence for performance of sonar dome. In this paper, Flow analysis is performed on vicinity of the sonar dome model using Large Eddy Simulation method. Also, direct method that extracts perturbational sound pressure, FW-H method without turbulence-induced noise and permeable FW-H method that is able to calculate turbulence- induced noise were compared in order to show turbulence effect.
