Global stability and resolvent analysis of sound emission in a high-Reynolds number turbulent jet
Abstract eng: Global stability and resolvent mean flow analyses of a Mach 0.9 high Reynolds number turbulent jet are conducted. The global We compared with wave packets distilled from a high-fidelity LES data base. The near-field and acoustic radiation of the linear global modes compare favorably with the simulation. Super-directive as well as multi-directive radiation patterns are observed. Since all global modes are stable, we conduct a resolvent analysis to characterize the noise amplifier behavior of the jet.
