title = "CFD predictions of Damk{\"o}hler number fields for reduced order modeling of v-gutter flame stability",
abstract = "Computational fluid dynamics (CFD) simulations have been used to extract flow and chemical time scale statistics in the wake of a v-gutter flame. These statistics are used to develop a method for using the local Damk{\"o}hler number as a predictor of local extinction. CFD predictions are validated by comparing non-reacting flow predictions to available experimental data around the v-gutter. Results are obtained for URANS, DES, and LES turbulence models. URANS reacting flow studies compare two different turbulent combustion models using a one-step global chemical kinetics mechanism. Flow time scale statistics from the different non-reacting turbulence models are compared with those from a URANS reacting model. All flow predictions are obtained using the commercial CFD software package FLUENT. Non-reacting LES and DES simulations showed better agreement with experimental data than URANS. Reacting simulations are used to compare non-reacting and reacting flow time scales, and to extract chemical time scale statistics.",
