Finite amplitude acoustic waves (FAAWs) that propagate in a two-dimensional rectangular duct of semi-infinite length as a result of periodic excitation are determined by using second-order perturbation, based on the partial wave analysis method. With second-harmonic boundary and initial conditions o

โฆ Synopsis
The propagation of spherically diverging acoustic waves of finite amplitude in fresh and sea water is considered. The calculation of the second and third harmonic distortion is obtained from the approximate solution of the non-linear wave equation in a dissipative medium.

The finite element approach has previously been used, with the help of the ATILA code, to model the propagation of acoustic waves in waveguides [A.-C.

The axisymmetric problem of the propagation of non-stationary waves from a spherical cavity in the plane of an infinite layer filled with an acoustic medium is considered. Using methods of incomplete separation of the variables in the space of Laplace transformation in time, the problem is reduced t
