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 […]
Plot of the month: Melbourne cricket ground redevelopment
Contributed by Eric Jal, Sr. Engineer, Energy Div. Connell Wagner, Melbourne, Australia Ventilation is a key design factor for the new Melbourne Cricket Ground (MCG). Using PHOENICS to optimize the design, CFD and Tecplot have been used to analyze air movement within the building and in external areas. In this image we see relative changes in air movement patterns across the pitch due to the construction of the new Northern […]
