Abstract: The problem concerning the propagation of sound waves in a binary mixture of monatomic ideal gases is studied by using a kinetic model of the Boltzmann equation which corresponds to the two-fluid hydrodynamic theory. Comparison of the sound propagation results with the available experimental data shows that the two-fluid model equation presented in this paper can be used to describe the acoustic properties of a binary mixture in a frequency range extending from the Navier–Stokes (or continuum) regime far into the transition regime.
