Numerical and Physical Modeling of the Response of Resonator Liners to Intense Sound and High Speed Grazing Flow
Amount: $599,808.00An aeroacoustic computational code based upon a numerical solution of the full Navier-Stokes equations will be developed to provide a deep understanding of the physical behavior of resonator liners ex ...
SBIRPhase II2010National Aeronautics and Space Administration -
Predictions of the Acoustic Nearfield on a Carrier Deck
Amount: $79,995.00On a carrier deck, navy personnel operate in close proximity to high-speed jets. They are, therefore, exposed to high intensity jet noise resulting in possible severe loss of hearing. The objective of ...
