Abstract: Abstract: [Objectives] To study the wind-induced noise of typical bar in open area of cruise ship. [Methods] Numerical simulation of aerodynamic noise and wind-induced vibration noise was carried out based on computational fluid dynamics combined with acoustic analogy method and acoustic-vibration coupling method to explore the generation mechanism and characteristics of the two kinds of noise. [Results] Under different wind speeds, the maximum frequency of aerodynamic noise is dominated by the vortex shedding frequency, and the maximum frequency of wind-induced vibration noise is dominated by the natural frequency of the structure. The aerodynamic noise of three different cross-section bars is generally greater than that of wind-induced vibration noise, and the aerodynamic noise of square bars is the largest. Under large flexibility, when the fluctuating pressure frequency of the rod is close to the natural frequency, the wind-induced vibration noise will be close to or even exceed the aerodynamic noise. [Conclusions] In the design of typical bar in open area of cruise, reasonable bar shape and size should be selected, and the vortex shedding frequency of bar should be avoided as close as natural frequency, so as to reduce wind-induced noise.
