Publisher Summary This chapter presents general considerations of autonomous
combustion oscillations. There are three general classes of combustion oscillations that may …

THIS note describes an investigation of the nonlinear interactions between natural acoustic
modes and forced oscillations in an unstable combustor. Such instabilities are a serious …

Combustion instabilities in modern high-performance propulsion systems are often
manifested as large amplitude pressure oscillations and can result in serious performance …

Publisher Summary This chapter discusses a few experimental and theoretical studies of
combustion oscillations. The frequency of organ-pipe oscillations in combustors of varying …

This paper, intended to complement Buckmaster's position paper on Combustion Instability,
examines the role of finite-amplitude gasdynamic disturbances on selected modes of …

Pressure oscillations during limit cycle operation for one constant operating point are
measured along the combustor length. The shape and amplitude of several independent …

Combustion roar is a “white” noise radiated from small regions in the flame which suddenly
burn. Single frequency oscillations of the simple acoustic type in the combustion chamber …

▪ Abstract Early work and recent advances in feedback control of combustion oscillations are
described. The physics of combustion oscillations, most commonly caused by a coupling …

Acoustic oscillations are often generated when gases are burned in combustion systems.
This phenomenon goes under various names, viz., unstable combustion, sonant …

WHEN combustion takes place within an acoustic res-onator, the interaction between
acoustic waves and unsteady combustion may lead to oscillations of damaging intensity …
