Abstract

Extra noise is generated when jets are installed beneath solid surface. In this paper, large-eddy simulation (LES) has been used to investigate these jet installation effects. The simulations were performed on two jet configurations: An isolated jet and a jet installed below a horizontal flat plate. The LES is compared with experimental data from measurements using hot wires, unsteady surface pressure sensors, and far-field microphones. Good agreement has been achieved between LES and experimental measurements on flow statistics, space-time correlations, and both near-field and far-field sound spectra. The installed effects are discussed from the perspective of flows and acoustics in the validation process.
