Abstract
In the frame of ventilation noise prediction and control the simulation of axial fan noise is still a challenge due to the high complexity of the aerodynamic phenomena involved. The objective of this paper is to provide a simplified technique for axial fan noise simulation based on a double approach: 2D BET or 3D CFD flow solution coupled with the BPM model for aeroacoustic model with 1/3 octave band and directivity noise predictions. Numerical noise predictions have been validated with experimental data available from literature achieving good results. Methodologies, limitations and potentialities of the approaches are discussed in order to shape a tool to be used for applied design and optimization of ventilation systems.
