Summary:

AbstractIn this paper, a sectional soot model coupled to a tabulated combustion model is compared with measurements from an experimental engine database. The sectional soot model, based on the work of Vervisch-Klakjic (Ph.D. thesis, Ecole Centrale Paris, Paris, 2011) and Netzell and others (P. Combust. Inst., 31(1):667-674, 2007), has been implemented into IFPC3D (Bohbot and others, Oil Gas Sci Technol, 64(3):309-335, 2009), a 3D RANS solver. It enables a complex modeling of soot particles evolution, in a 3D Diesel simulation. Five distinct source terms are applied to each soot section at any time and any location of the flow. The inputs of the soot model are provided by a tabulated combustion model derived from the Engine Approximated Diffusion Flame (EADF) one (Michel and Colin, Int. J. Engine Res., 2013) and specifically modified to include the minor species required by the soot model. An experimental database has been built, using both commercial Diesel fuel and the computed surrogate (30% alpha-methylnaphthalene and 70% decane in volume) to compare result between the Diesel fuel and the surrogate and to validate the models against the experiment. Globally, the results are satisfactory and show an improvement against the current standards
