Numerical simulation study on noise reduction of underwater multi tube low-speed bubble flow exhaust
Year: 2025
Type: conference-paper
Abstract: Numerical simulation of an underwater single-tube and multi-tube low-speed bubble flow exhaust process and acoustic signals based on the fluid volume model (VOF) and Williams Hawkins (FW-H) model is conducted to study the acoustic signals and noise reduction mechanism of multi-tube low-speed bubble flow exhaust process. Compare the simulation results with a theoretical basis to verify the applicability and accuracy of the model. The research results indicate that multi-tube exhaust can significantly reduce pressure fluctuations caused by bubble detachment from the pipe mouth, and can reduce the amplitude of noise in the mid to low frequency range.
