AN EXPERIMENTAL INVESTIGATION OF TURBULENCE-EXCITED PANEL VIBRATION AND NOISE (BOUNDARY-LAYER NOISE)

Abstract

A study is made of the flexural motion and noise generated by 11 x 11 in. steel panels flush mounted in the wall of a turbulent flow channel. The mean square exciting pressure fluctuation at the wall, its spectral density, and two- point correlations of the pressure were measured with the use of pinhole microphones. The flexural response of sample panels was studied by correlation techniques. The calculated relief plot of correlation shows qualitative agreement with the experimental results.
