✦ Synopsis
ities, property-estimation methods, dispersion modelling, and correction to the k-¢ model. Considerable differences were found in fuelvapour distribution when using different models, The LIF measurements and the numerical simulations were compared in terms of the fuel-vapour distribution. The simulation results were found to be very sensitive to the initial SMD, in particular in the presence of air swirl. Inaccuracies in the estimated SMD, therefore, constitute th e primary accuracy limitation of the simulation. By adjusting the SMD, in many cases good agreement between measurement and simulation could be obtained. Remaining discrepancies that cannot be attributed to SMD adjustments are supposed to originate either from a turbulencemodelling error and the occurrence of secondary droplet breakup, which was not modelled, or, on the other hand, to the error by assuming a proportionality between LIF intensity and fuel oil concentration.
