On 36 forms of the acoustic wave equation in potential flows and inhomogeneous media, On 24 forms of the accoustic wave equation in vortical flows and dissipative media

Junho 2007

The classical wave equation applies to the propagation of sound waves that are (i) linear are of small amplitude, (ii) in the absence of dissipation, (iii) in a steady and homogeneous medium (iv) at rest. The paper proves 60 extensions of the classical wave equation for sound in more general conditions, including: (i) non-linear or large amplitude waves; (ii) dissipation by viscosity and thermal conduction; (iii) media whose properties depend on position (inhomogeneous) and/or time (unsteady); (iv) moving media including potential, compressible, sheared and swirling mean flows.
