Large-eddy-simulation prediction of an installed jet flow and noise with experimental validation
Large-eddy-simulation prediction of an installed jet flow and noise with experimental validation
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.

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.
