Abstract:

The PI was successful in the proposed effort to develop robust methods for producing regime maps in the transition to MILD combustion. While this approach is an improved method to classify flames, the applicability of generalized regime maps at predicting the appearance of turbulent flames is limited without a-priori knowledge of the flow-field. The PI identified the importance of minor species, formaldehyde CH2O. CH2O plays a critical role in flame stabilization under MILD combustion conditions. Additionally, equilibrium levels of OH in the oxidant stream needs to be considered in modelling of these flames. The results from calculations of simplified reactors can be applied to more complex and realistic flame conditions, providing the temporal andor spatial effects are taken into consideration. Computational models of jet flames can reproduce experimental trends, including a-priori predictions. Finally, a new burner has been developed to facilitate future experimental campaigns of flames in a vitiated coflow including MILD combustion under elevated pressure conditions up to 10 bar. The PI was very successful with 19 publications as a direct result of the research grant.
