Response of strings to turbulence—Redux (L)
1.R. H. Lyon, “Response of strings to random noise fields,” J. Acoust. Soc. Am. 28, 391–398 (1956) (available on Disc #1, JASA Archives on CD-ROM).
2.As explained in Ref. 1, the “string” is a thin strip of steel (10 mils by 3/16 in., 44 cm long under tension, excited by airflow along its length in a tube. Motion was observed by an optical arrangement that measured the string deflection.
3.In a cross-correlation experiment, the output is that of a correlation detector where the reference is the signal from the upstream sensor. The time delay for the envelope of the output signal is determined by the signal or group delay of the system (in this case, the unknown dynamics of the turbulent flow). This delay is usually expressed in terms of a convection velocity by dividing the separation distance of the sensors by the time shift of the correlation peak.
