Abstract
The Coppens-Sanders theory for the one-dimensional, nonlinear,
acoustic wave equation with dissipative term describing the viscous
and thermal energy losses encountered in a rigid-walled, closed tube
of large length-to-diameter ratio was applied to finite-amplitude
standing waves by the use of the Fast Fourier Transform. Computer
programs were written to determine the amplitudes and phases of the
first 255 harmonics. Curves of harmonic distortion as a function of
the strength parameter were found to be in excellent agreement with
available experimental data, to agree with the Coppens-Sanders
perturbation analysis, and to extend the theoretically describable
regime closer to strengths leading to the formation of the shock front.
