Abstract

A test campaign has been carried out in which a complex jet field was experimentally investigated in an anechoic chamber. Stereo PIV measurements were acquired over a series of planar locations in this supersonic flow-field, simultaneously sampled with pressure transducers embedded in the jet and far-field microphones in the anechoic chamber. Due to the high mass flow rates (∼ 2.0 kg/s), nozzle pressure ratios (NPR = 4.25), and Reynolds number (Re = 2.74 ×106), various calibration challenges in the PIV instrumentation were encountered. The solutions employed to overcome these difficulties are first presented. After establishing confidence in the measurements, the full dataset is presented through planar and volumetric views. Statistical moments and Reynold stresses reveal a complex evolution of the turbulence and shock structures, which dominate this flow. By establishing the validity of the simultaneously acquired pressure and acoustic data, future studies will use this dataset in aeroacoustic analyses of the jet.
