Traditionally, blowout is described as loss of static stability of a combustion system whereas thermoacoustic instability is seen as loss of dynamic stability of the system. The above description follows from the analysis of the stability of the flame. At blowout, the system transitions from a stable reacting state to a no-reaction state indicating the loss of static stability of the reaction. At instability, the flame is dynamically unstable and the reaction rate exhibits periodic oscillatory behavior. However, this simple description of stability margin is inadequate since combustors exhibit various nonlinear behaviors at the transition regimes for either phenomenon. Recently, it was shown that combustion noise, the ‘stable regime’ according to the concepts of stability, is by itself dynamically complex and exhibits multifractal characteristics. Considering this, researchers have already described the onset of combustion instability as loss of multifractality. In this work we will provide a multifractal description for lean blowout in combustors with turbulent flame, thereby bringing in a common framework to describe both thermoacoustic instability and lean blowout. Further, we will also introduce a method for predicting blowout based on the multifractal description of blowout. © 2015 American Institute of Aeronautics and Astronautics Inc, AIAA.
