Analysis and Low-Order Modeling of Interactions between Acoustics, Hydrodynamics and Premixed Flames

233 Seiten, Dissertation Technische Universität München (2019), Softcover, B5

Zusammenfassung / Abstract

This doctoral thesis analyzes interactions between acoustics and lean premixed flames from a thermoacoustic point of view. Special focus is put on the linear response of the global heat release rate of burner-stabilized laminar flames to acoustic perturbations. To this end, a first principle-based low order modeling framework is developed, which allows to separately investigate well-defined aspects of the underlying dynamics. High fidelity numerical simulations provide instructive validation data.
