What is it about?
The interaction between flow, structure, and sound is a key factor in the generation and development of hydrodynamic noise in underwater vehicles. To elucidate the exploration of existing research in this area, we conducted a review study to summarize the current status of flow-structure-sound coupling research and further propose development recommendations for future research in related fields.

Why is it important?
Current research on fluid-structure-acoustic coupling effects remains immature. Additionally, due to the complexity of modeling such coupling, noise reduction technologies struggle to comprehensively account for its impacts. Furthermore, complex operating conditions significantly reduce the stability of noise reduction outcomes, preventing existing techniques from achieving optimal performance. This review addresses these challenges to guide future research, providing theoretical and data-driven support for low-noise hull design, drag reduction, vibration mitigation, and the application of novel materials and low-noise structures in underwater vehicles.
