Predictions of soot and thermal radiation properties in confined turbulent jet diffusion flames
- Cranfield Univ., Bedford (United Kingdom). School of Mechanical Engineering
Computational modeling of well-documented jet diffusion flames, burning methane at atmospheric and elevated pressure, is presented. The main emphasis of the work is on the intimate coupling between the soot production of rate and the flame radiative heat loss. This coupling is found to be vital for flame soot prediction. A number of methods for closing soot production source terms in the turbulent flow are presented and assessed. In particular it is shown that the degree of correlation assumed between soot particles and their oxidizing species exerts a large influence on both the growth of the soot and its subsequent burnout. Finally, predictions of the mean radiative emission spectra from these flames are presented.
