Conditional moment closure modelling for spark ignition in a turbulent n-heptane spray

Richardson, E.S. and Mastorakos, E. (2007) Conditional moment closure modelling for spark ignition in a turbulent n-heptane spray At 5th Mediterranean Combustion Symposium, Tunisia. 09 - 13 Sep 2007.

Record type: Conference or Workshop Item (Paper)


Ignition and flame stabilisation have been simulated in a turbulent, bluff body stabilised spray flame. A complete first order Conditional Moment Closure (CMC) model for spray combustion is presented, as well as CMC modelling for spark ignition. The new elements of the two phase model formalism and the spark ignition models are illustrated using a one dimensional spray ignition example. It is shown that the new spray terms are not significant in the flows considered, however the modelling of the mixture fraction variance equation is critical. Finally, ignition of the experimental spray burner is simulated and compared with the available data, showing reasonable qualitative agreement but over-predicting the speed of flame stabilisation.
