Abstract

A one-dimensional analytical model with highly simplified single-step kinetics is shown to describe spatial and global behaviors exhibited by swirl stabilized combustors responding to acoustic forcing. Turbulent time scales are taken to be quick relative to the forcing time scales, relieving the model of the responsibility of resolving the flamelet response, and instead allowing a formulation of the flame as a turbulence-thickened reaction region. Rather than reaction rate intensity, volumetric fluctuations of the reaction region are shown to make quantitative predictions that agree with published data.
