520 ▼a We use input-output analysis to predict and understand the aeroacoustics of high-speed turbulent jets. We consider linear perturbations about Reynolds-averaged Navier-Stokes (RANS) solutions of ideally expanded, axisymmetric, compressible turbul
520 ▼a Far-field acoustics generated from turbulent jets are further modeled, using a Ffowcs Williams-Hawkings (FW-H) solver implemented directly within linear input-output analysis framework. Our hybrid input-output/FW-H method efficiently connects in
520 ▼a To distill acoustically relevant sources, input forcings are further restricted by introducing a new weighting matrix, which selects forcing functions only in the region that contains high turbulent kinetic energy (TKE). We then find that input
