Research goal
In the context of thermoacoustic instabilities, it is essential to predict and analyse the dynamic response of a flame to flow perturbations. Various types of flow perturbations are relevant, e.g. modulation of velocity, swirl or equivalence ratio. Analytical models for laminar flame dynamics provide important insight into flow-flame interaction mechanism allowed to identify relevant time scales. For turbulent flames, a combination of Large Eddy Simulation of reactive flow with system identification provides quantitative information for configurations of applied interest. Recent interest focuses on spray flames.
Hypothesis
The forced response of a flame is relevant for the study of self-excited combustion instabilities.
