The Coppens- Sanders perturbation solution for the one- dimensional
non- linear acoustic wave equation with dissipative term describing
the viscous and thermal energy losses encountered in a rigid walled,
closed tube with large length-to-diameter ratio was extended to include
sixth order terms. The solution was then investigated to determine
the region of validity. Computer programs were written to evaluate
and graph the resulting waveforms. Available experimental results
were compared with the theoretical predictions and good correlation
was found to exist in the region of low Mach numbers. This agreement
was found to gradually deteriorate as the Mach number was increased.
A Fourier synthesis approach is also presented and the leading terms
of the first ten harmonics are derived.
