abstract

This paper involves a theoretical analysis of the propagation of sound within chemically reacting hydrocarbon combustion products. A new procedure for determining the sound speed and absorption coefficient was developed. Using a similar approach can do analyses for other chemically reacting gas mixture. One-dimensional sound propagation was assumed. Molecular diffusion effects, such as viscous stress, heat conduction, and mass diffusion were appropriately neglected along with possible effects due to vibrational non-equilibrium. In this way only the effects of chemical reactions on sound propagation was considered. The expressions for sound speed and absorption coefficient were derived as a function of frequency.
