Abstract
Finite-amplitude standing waves in air at ambient temperature
contained in a rigid-walled rectangular cavity were experimentally
investigated. The pressure waveform in the cavity was analyzed for
harmonic content and compared to the theory of Coppens and Sanders
as modified to include empirical losses. The waveforms for the
nOO and OnO configurations were analyzed at strength parameters of
about 0.5, 0.75, and 1.0, where the strength parameter is defined as
MQ₁(y+1)/2. M is the Mach number of the fundamental, Q₁ is the
quality factor of the fundamental resonance, and y is the ratio of
specific heats. It is found that the theoretical model accurately
predicts the shape and approximates the amplitudes of the harmonic
components of the finite-amplitude standing waves.
