| The prediction of the flow-induced noise of the underwater counter-rotation propeller is of great significance for the feature extraction, classification and identification of underwater targets. The turbulent flow field caused by the rotation of the blades is the noise source of underwater counter-rotation propeller. The hydrodynamic noise mechanism and research progress are presented which caused by the turbulent boundary layer pulsation, rotational interference effect and cavitation effect of the underwater counter-rotation propeller. The characteristics of the three propeller noise prediction methods in the current engineering application are compared. Based on the analysis of the difficulty of numerical prediction of the flow-induced radiated noise, the research progress of the calculation method of the flow-induced noise is reviewed. It is pointed out that the indirect numerical simulation method is an effective method for predicting the flow-induced noise in the engineering. |
