Book Description
The near field fluctuating pressure and aerodynamic mean flow characteristics of a cold subsonic jet issuing from a contoured convergent nozzle are presented. The data are presented for nozzle exit Mach numbers of 0.30, 0.60, and 0.85 at a constant jet stagnation temperature of 104 F. The fluctuating pressure measurements were acquired via linear and semi-circular microphone arrays and the presented results include plots of narrowband spectra, contour maps, streamwise/azimuthal spatial correlations for zero time delay, and cross-spectra of the azimuthal correlations. A pitot probe was used to characterize the mean flow velocity by assuming the subsonic flow to be pressure-balanced with the ambient field into which it exhausts. Presented are mean flow profiles and the momentum thickness of the free shear layer as a function of streamwise position.Ponton, Michael K. and Ukeiley, Lawrence S. and Lee, Sang W.Langley Research CenterAEROACOUSTICS; CONVERGENT NOZZLES; JET FLOW; SUBSONIC FLOW; HIGH REYNOLDS NUMBER; PRESSURE OSCILLATIONS; FLOW CHARACTERISTICS; ENGINE NOISE; EXHAUST NOZZLES; EXHAUST GASES; MACH NUMBER; PRESSURE MEASUREMENT; PRESSURE DISTRIBUTION; NOISE REDUCTION; FLOW VELOCITY; MOMENTUM; EXHAUST VELOCITY...
