Calculation of sound pressure level of marine propeller in low frequency

Calculation of sound pressure level of marine propeller in low frequency

The research performed in this paper is carried out to calculate the sound pressure level of the marine propeller by Reynolds-Averaged Navier–Stokes solver in low frequencies band. Noise is generated by the induced trailing vortex wake and induced pressure pulses. The two-step Fflowcs Williams and H...
