Conditional Moment Closure (CMC) Predictions of a Turbulent Methane-Air Jet Flame

摘要

Conditional Moment Closure (CMC) predictions are made for a turbulent jet diffusion flame of a methane-air mixture. They are compared with laser diagnostic measurements for the velocity and mixing fields and temperature and species mass fractions including nitric oxide, NO. In general, results show good agreement for the flow and mixing field, but predictions for the radiation loss from the flame are much higher than those measured directly. Predictions for the conditional average mass fractions of the major species and of the temperature show good agreement with the measurements on the fuel-lean side of stoichiometric.
