摘要：
A Large Eddy Simulation/Conditional Moment Closure calculation of forced ignition of a turbulent bluff-body stabilised non-premixed methane flame is performed and the results are qualitatively investigated to assess the suitability of this model for highly transient combustion phenomena. The qualitative features of the flame expansion process agree with experimental findings. Quantitatively, the time for the establishment of the whole flame is under-predicted, which could be improved by using a finer CMC grid.
