Numerical investigation of swirling kerosene spray flames using Large Eddy Simulation

The present paper describes the results of a Large Eddy Simulation of swirl stabilised flames fuelled by liquid kerosene. Two-flames are examined, denoted Flame A and Flame B for which experimental data is available. Flame A is a stable flame while Flame B is characterised by a lower air-to-fuel ratio that is close to the blow-off limit. An LES-spray-pdf methodology is applied to high-swirl reacting spray flows and the results are compared with measured temperature and species concentrations. The formulation accounts for the sub-grid turbulence-spray-chemistry interactions and the coupling between the continuous and dispersed phase.
