Sound absorption and dispersion in dilute polyatomic gases: a generalized kinetic approach.
In: Journal of Statistical Mechanics: theory and experiment, (08), [Article]

Abstract

A generalized kinetic model equation which takes into account the frequency dependence of the thermal conductivity is used to analyze the problem of sound propagation in dilute polyatomic gases. By comparing the theoretical results with some available experimental data we infer that our model equation provides a precise transition between low- and high-frequency limits.
