NASA CFD Software Helps Quiet the Skies

Contributed by: Dr. Craig Hunter, NASA Langley Research Center Noise Sources in a Jet Plume The jet plume in Figure 1 originates from a bypass ratio (BPR) typical of a transport aircraft. Noise sources are shown in a 12,500 Hz frequency band (sub-scale) with the observer at 88 degrees to the inlet. The data set has about 35 variables at 17 million cells. The bypass ratio relates the size of […]
