Sound propagation in binary gas mixtures
Abstract
The propagation of a sound wave through a monatomic binary gas mixture of arbitrary composition was studied using the model equations proposed by Hamel. A set of six simultaneous algebraic equations was derived containing the unknown wave speed and absorption coefficient. Simple expressions for wave speed and absorption coefficient were obtained for the limiting case when the sound frequency is much less than the mean collision frequency. The results were compared to Kohler's formula and to existing data.
