[内容简介]Phenomena referred to generally as combustion instabilities are fundamentally related to the stability of motions in a combustion chamber. Their existence is normally inferred from observations of well defined oscillations of pressure or structural distortions. Instabilities of combustion processes themselves are rarely contributing factors, the chief exceptions being possible intrinsic instabilities of solid propellants, and the weakening of flame stabilization mechanisms near the lean operating limits of gaseous and liquid fueled systems. Broadly, then, the appearance of a combustion instability is due to a loss of stability of the composite dynamical system comprising the combustion processes and the chamber itself, containing the medium which supports waves associated with the unstable motions.
