A definition of acoustic power in conservation form in lined infinitely long uniform ducts is extended to include axially symmetric non-uniform ducts with potential mean flow and finite length lining. The definition includes a contribution at the lined boundary. Benchmarking is accomplished by verif
The reflection and refraction of a plane acoustic wave by a thermoelastic plane layer, non-uniform in thickness, bounded by non-viscous heat-conducting liquids, generally different, is considered. The system of equations for small perturbations of the thermoelastic medium is reduced to a system of o
Standing longitudinal acoustic waves in a non-uniform gas within a chamber are studied. Frequencies and wave forms are calculated for various types (linear and exponential) and degrees of non-uniformity in the speed of sound. Little changes in wave forms but significant changes in frequencies are co
