Title:
Acoustic characterisation of double-orifice configurations by means of a LES-SI approach 
Abstract:
A numerical study of the aeroacoustic properties of a pair of orifices placed in a duct is here presented. Two geometric configurations with two different distances in between the orifices have been analysed to consider conditions with or without tonal noise sources. A Large Eddy Simulation has been performed and validated with respect to experimental measurements for both aerodynamic and acoustic predictions. Data series from an acoustically excited LES have been post-processed through System I...    »
