Experimental and Computational Study of Tones Occurring with a Coaxial NozzleTones were encountered in large-scale, multi-stream nozzle tests in the Aeoacoustics Propulsion Laboratory (AAPL). A different coaxial nozzle used in a past experiment also produced tones. In this paper, we present experimental and COMSOL results addressing the tone mechanism in the latter nozzle.
