The acoustic energy conservation law in presence of flow can be very effectively expressed with the help of two variables: the acoustic mass velocity and the acoustic exergy. The minimal and maximal ratio of the dissipated or generated acoustic power over the incident acoustic power are computed from the scattering matrix of an acoustic element. This method is applied to a diaphragm and to a laminar element in presence of flow. It is shown that the results provide indication for the physics of… Expand
