Chemical-Acoustic Interactions in Combustion Systems.
Abstract
A review is presented of chemical-acoustic coupling in terms of its role as a basic interaction which can alter the behavior of combustion systems. Effects resulting from this interaction include sound amplification, changes in sound speed and frequency, sound-induced changes in reaction rates, and acoustic stimulation of chemical oscillation and instabilities. Such effects are important in a variety of problems including combustion instability in jet and rocket engines, the structure of propagating detonations, and turbulence in chemically reacting flows. Background material is presented starting with the early work Lord Raleigh and continuing into a discussion of the relevant properties of sound waves. This leads to a discussion of the influence of energy release on sound waves and the influence of sound waves on chemical reactions. The conclusion is a discussion of chemical-acoustic coupling in combustion environments.
