Abstract

Extra noise is introduced when jets are installed under a solid surface. In the paper, Large-Eddy Simulation (LES) has been performed to investigate the installation effects. The simulations on two jet configurations are presented: one isolated jet and one installed jet with L/D = 4 and H/D = 1. The LES is compared with experimental data from both hot wire and microphone measurements. Good agreement has been achieved between LES and experimental data on flow statistics, near-field spectra, space-time correlations and far-field sound spectra. The installed effects are also discussed from the perspectives of flows and acoustics.
