This paper focuses on a numerical algorithm for analyzing flow-induced noise of composite plates. In this study, a method based on the superposition of uncorrelated plane waves was proposed to synthesize turbulent fluctuating pressure and calculate flow-induced noise using the finite element acoustic-vibration coupling module. The detailed theory and procedures of this algorithm were provided for rectangular plates as an example. The computational results were compared with analytical theory to validate the accuracy of the algorithm. Based on the wave number filtering principle, the criteria for selecting the truncation wave number was given, and the algorithm was compared with traditional methods in terms of computational efficiency, demonstrating the advantages of the algorithm in computational efficiency and accuracy. Finally, the mechanism of flow-induced noise generation in composite plate structures with acoustic coating was analyzed in this paper using the proposed algorithm, providing theoretical support for reducing flow-induced noise of underwater vehicles.
