Experimental Study of Finite-Amplitude Standing Waves in Rectangular Cavities with Perturbed Boundaries.

Abstract

Finite-amplitude standing waves in air at ambient temperature contained within a tuneable, rigid-walled rectangular cavity were experimentally investigated. The effects of various geometrical perturbations on the harmonic content of the observed pressure waveform in the presence of degeneracies were compared to theory. Theory and experiment agreed qualitatively in that shape of the resulting curves have the correct form, but significant differences in the level of the second harmonic were frequently observed.
