Abstract

Taking a cruise thruster as the research object, the sound pressure distribution in the flow field of the thruster is obtained through CFD calculation and analysis. The calculation results show that the axial frequency energy is more sensitive to the incoming flow velocity. Due to the existence of the side thruster channel, the dynamic and static interference is formed between the propeller and the channel wall. The calculation results show that the closer to the leaf tip, the higher the energy of leaf frequency and its doubling. The research results can provide important reference data for the optimization design of thruster structure, and have certain engineering practical value.
