Investigation of Ducted Fan Noise: from Data-driven Modelling of Wall Pressure Spectra to the Effects of Distorted Inflows KU Leuven
The acoustic emission of small ducted fan systems within heating-ventilation and air conditioning applications is a growing concern due to the ever-increasing regulations and the thriving interest of customers in quieter environments. This research focuses on the noise emission of small ducted axial and centrifugal fans found in those products. The noise generated by an axial fan for moderate inflow turbulence and at high frequencies is ...
