NUMERICAL SIMULATION OF THE ROTOR TRAILING EDGE NOISE
Abstract and keywords
Abstract (English):
The paper presents numerical simulation of trailing edge noise. This noise is due to the interaction of turbulence boundary layer on rotor blade with its trailing edge. Noise prediction is performed using a semi-analytical broadband noise model based on the Amiet model. Modeling of surface pressure caused by a turbulent boundary layer is performed using various semi-empirical models. The developed model well reflects the trend of the general spectral characteristics at high and low frequencies. The simulation results depend on the choice of the surface pressure spectrum model.

Keywords:
surface pressure spectrum, trailing edge noise
