- W2012989481 abstract "Whilst the most general methodology to predict jet noise utilises Direct Numerical Simulation or Large Eddy Simulation to model the full unsteady ∞owfleld, such an approach is unfeasible in an engineering context. A method is proposed to couple a standard Reynolds Averaged Navier-Stokes CFD method with a Lighthill based noise model for coaxial jets. This has relatively low computational resource requirements, whilst possessing the physical mechanisms to re∞ect how changes in nozzle geometry modify the noise spectra. The three parameters in the noise model were calibrated using single stream jet noise data and then applied to coaxial jet ∞ows. Coplanar coaxial jet problems for difiering area and velocity ratios showed reasonable agreement with measured noise spectra. However, a three-quarter cowl nozzle conflguration showed poor agreement with experiment. Serrations added to the nozzle produced only small changes in the turbulence intensity and length scale predicted by the RANS CFD model and consequently only minor changes were observed in the spectra - a reduction in low frequency noise coupled with an increase at higher frequencies." @default.
