Abstract

The refurbishment of the 7, 300ft 3 anechoic chamber located at Syracuse University for studying aerodynamically generated noise is discussed. The purpose of the facility is to provide free field conditions for an experimental study aimed at the identification and control of the noise producing events in the shear layer of a cold (104°F), 2in. diameter, Mach 0.85 jet. The facility is updated with intentions of performing future studies at elevated temperatures near 1000°F. Safety issues are discussed because of the elevated temperatures, as well as concerns for ensuring acoustical quality in the chamber due to the addition of a new Make-Up Air unit. Several far field acoustic measurements are acquired over a range of Mach numbers and facility conditions in order to quantify the acoustic performance of the facility. Pitot-static measurements of the jet's plume, obtained at several streamwise locations, are shown and compared with the mean statistics from a stereo PIV system. Instantaneous PIV vector maps of the r - θ plane at Mach 0.85 and z/D = 2 through 7 are shown to illustrate the rich turbulent character of the flow from a compressible axisymmetric jet.
