We provide prediction methods and perform analysis
- The propeller cavitation noise level is estimated using Brown's formula:
- SPL = K+10 Log (BD4N3f −2)+ 10 Log (Ac /AD )(dB re 1 μ Pa/√Hz)
- For Propellers:K = 163、For Thrusters:K = 170
- B : Number of Blades 、D : Diameter (m)、N : Revolution Rate (rps)、f : Frequency (Hz)
- Ac : Cavity area (swept)
- AD : Propeller Disk Area (m2)
- We provide a program for estimating propeller cavitation noise levels based on CFD and bubble dynamics. We also perform calculations on your behalf.
Propeller cavitation noise model and bubble dynamics, calculation results.
- We can also utilize other prediction methods to improve accuracy.
