Abstract / Description of output
A common approach to modeling nonlinear behavior in acoustic tubes of variable cross section is
to use an uncoupled travelling wave solution whose profile distorts progressively - the distortion
occurs due to changes in wave speed, which is a result of the nonlinearity within the system.
However, these uncoupled solutions neglect a) any interaction between the waves, even in the
cylindrical case, and b) any scattering effects due to changes in cross sectional area. This paper
attempts to identify what effect this separation of travelling wave solutions has compared to a
coupled-wave solution. This is done with simple numerical time stepping methods for case a) to
show the overall deviation of the solution when interactions are neglected. For case b) dispersion
analysis is used on the linearized system to highlight the effect of scattering on the dynamics of
the system.
