Abstract
The eddy dissipation concept (EDC) model has the ability to incorporate detailed chemistry in turbulent combustion, which makes it attractive for simulating a wide range of industrial combustion systems. However, its application for modeling weakly turbulent reacting flows and slow chemistry poses a real challenge. The present study examines the influence of the EDC model’s coefficients, with respect to turbulent flow field characteristics. In order to assess the sensitivity of EDC model’s constants, simulations of two distinct jet flames covering weakly and highly turbulent flow conditions are performed. The predictions are compared with published experimental measurements. The findings of this study revealed that EDC predictions of the characteristics of weakly turbulent reacting flow can be improved by changing the model’s constants. The study also showed that, in comparison with the standard EDC, modifying the model’s coefficients produced improved predictions of the characteristics of highly turbulent reacting flow regions. The conclusions of the analysis carried out in this study are used to simulate the gas-phase combustion of a small-scale biomass furnace using the EDC model, which is presented in the companion paper for this study.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
