(University of Waterloo) Date 2016 Abstract We report on a comparative study of model predictions of jet-in-hot-coflow flames. TheDelft Jet-in-Hot- Coflow (DJHC) burner was built to mimic the important characteristics of flameless combustion without the complications of a real furnace [1,2]. The DJHC burner has been used to create a turbulent diffusion flame of Dutch Natural Gas in a coflowing oxidizer stream of high temperature with low oxygen concentration. The experimental database contains the results of high speed chemiluminescence imaging, velocity statistics from LDA measurementsand temperature statistics from CARS measurements. In recent years several computational studies have been made using the DJHC burner as validation database [3-9]. It has been shown before that predictions are sensitive to the coflow radial profiles of temperature and oxygen concentration, to there presentation of effects of entrained air, and to turbulence-chemistry interaction and this is also the focus of the present study To reference this document use: http://resolver.tudelft.nl/uuid:94f228dc-5aa9-4048-8589-86f4bade8aed Event Combura 2016, 2016-10-05 → 2016-10-06, Soesterberg, Netherlands Part of collection Institutional Repository Document type abstract Rights © 2016 D.J.E.M.
