Abstract
The noise from turbulent, hot, supersonic jets during take-off and landing, as well as high-Mach cruise at altitude, dominates noise emanating from other powerplant components (e.g., fan, combustor). This intense noise has significant safety implications for launch personnel as well an environmental impact in the form of noise pollution around military installations. The proposed Phase II work will build on the successful Phase I effort to create a production CAA/CFD code which can accurately resolve the unsteady structures related to the dominant noise sources of high speed jets in realistic configurations. This software will predict the flow in and around realistic nozzle configurations and accurately capture the shock-containing jet plumes to enable physics-based noise predictions for these flows that include both jet mixing and shock-associated noise. The resulting software will enable the Navy customer to better design and engineer nozzle components and noise attenuation technologies for the low-bypass ratio powerplants of modern tactical aircraft.
