To calculate expected noise levels associated with turbine rotor motion.
State of Florida
Boca Raton, FL (computer modeling)
Seek to understand water turbine noise generation and to make preliminary estimations of noise levels.
This research is complete.
- Harmonic noise due to load fluctuations on a rotor blade (as it passes through a structural flow shadow) was found to be well below ambient levels at frequencies above about 10 Hz.
- Streamlining upstream structure increases noise levels at higher frequencies (20-30 Hz)
- Noise levels vary inversely with structure-rotor separation
