Abstract
Purpose
A numerical study on the aerodynamic noise generation of a high efficiency propeller is carried out.
Design/methodology/approach
Three-dimensional numerical simulation based on Reynolds averaged N-S model is performed to obtain the aerodynamic performance of the propeller. Then, the result of the aerodynamic analysis is given as input of the acoustic calculation. The sound is calculated using the Farassat 1A which was derived from Ffowcs Williams–Hawkings equation and is compared with the measurements.
Findings
Moreover, the fan is modified for noise reduction by changing its geometrical parameters such as span, chord length and torsion angle.
Originality/value
The variation trend of aerodynamic and acoustic are compared and discussed for different modification tasks. Some meaningful conclusions are drawn on the noise reduction of propeller.
