Summary

The final two chapters treat the response of flames to forced disturbances, both time-harmonic and random. This chapter focuses on local flame dynamics; i.e., on characterizing the local space–time fluctuations in flame position. Chapter 12 treats the resulting heat release induced by disturbances, as well as sound generation by heat release fluctuations. These two chapters particularly stress the time-harmonic problem, with more limited coverage of flames excited by stochastic disturbances. This latter problem is essentially the focus of turbulent combustion studies, a topic which is the focus of dedicated treatments [1–3].
