“…Due to the complexity of the motion, it has been difficult to express the turbulent motion accompanied by mass and heat transfer theoretically and numerically so far. The numerical simulation methods of turbulence include direct numerical simulation (DNS), large eddy simulation (LES), and Reynolds averaging method [4][5][6][7][8][9][10].…”

Hydrodynamic noise is one of the three major noise sources of submarines, which has a great impact on the concealment of submarines. Using the finite element method, the submarine is modeled, and the sound pressure distribution at various monitoring points of the submarine under different diving angles is studied. The results show that the sound pressure at each monitoring point of the submarine is small when the diving angle is about 10°, which provides a certain reference for the submarine’s covert navigation.

“…Hydrodynamic noise has a significant impact on the self-noise of submarines and has become the main noise source at higher speeds [1][2][3][4][5][6][7]. Therefore, the research on the control of hydrodynamic noise is of great significance from the perspective of reducing the self-noise of submarines and improving their detection ability [4]; The hull is an important part of the submarine structure.…”

“…The subject of studying aerodynamic noise is called aeroacoustics. With the development of modern computing technology and capabilities, from reducing aircraft jet noise to controlling takeoff and landing noise, specific aircraft noise issues faced at different times have promoted the research progress of aerodynamic acoustics and led to the emergence of computational aeroacoustic (CAA) theories, methods, and techniques [6].…”

The hull is an important component of the submarine structure, and it is also one of the factors that affect the concealment of the submarine. By using the finite element method, a submarine model was established to analyze the hydrodynamic noise at the contact points between the front and rear of the hull and the hull under different diving angles. The results show that when the diving angle is about 10°, the hydrodynamic noise at the front and rear positions of the enclosure is relatively small. The research results provide a reference for ensuring the stealth operation conditions of submarines and have practical significance for improving the stealth of submarines.
