Designing future ultra-high efficiency, ultra-low emission engines requires an in depth understanding of the multiscale,multi-phase phenomena taking place in the combustion chamber. The performance of the fuel deliverysystem is key in the air fuel mixture formation and hence the combustion characteristics, however in most spraymodelling approaches is not considered directly. Thus, it is important to understand how the selection of modelsthat mimic injection process affect predictions. In this paper we present an Eulerian-Lagrangian framework basedon OpenFOAM libraries to model spray injection dynamics. The framework accounts for primary droplet formation(based on a parcel method with predefined initial droplet size distribution), secondary droplet breakup, evaporationand heat transfer. In order to account for the interaction of droplets with turbulence, simulations were performedwithin the LES context with two different turbulence models. A systematic variation of the key injection parameters(parcel number, parcel size distribution) of the parcel method as well as the grid size was considered. Varying theparcel number affects the initial droplet size distribution which in turn, depending on the selection of the turbulenceand the evaporation sub-models, affects: spray dispersion; spray penetration; and subsequent droplet size distribution.Results were validated against the baseline experimental data for evaporating ECN Spray A with n-dodecanechosen as a surrogate for Diesel fuel.DOI: http://dx.doi.org/10.4995/ILASS2017.2017.4703

A new multi-orifice effervescent atomizer used for fire fighting was developed. The droplet size distribution of the spray produced by the nozzle was measured by laser Doppler particle analyzer. And the influence of liquid injection pressure, water flow rate and atomizer internal geometry was studied.
