A New 0D Diesel HCCI Combustion Model Derived from a 3D CFD Approach with Detailed Tabulated Chemistry

Abstract: Résumé -Un nouveau modèle 0D pour la simulation de la combustion Diesel HCCI obtenu par réduction d'un code CFD 3D utilisant une méthode de chimie complexe tabulée -Cet article présente une nouvelle approche phénoménologique 0D à la modélisation numérique de la combustion Diesel HCCI. Le modèle a été obtenu par réduction du modèle CFD 3D TKI-PDF (Cinétique Chimique Tabulée pour la détection de l'auto-allumage couplée avec une Fonction à Densité de Probabilité présumée) développé à l'IFP ; sa formulation est ba… Show more

“…injection systems performing complex injection strategies, low pressure and high pressure EGR loops,…) and then to describe the pollutant emissions formation processes, like CO and NOx, whose chemical kinetics depends strongly on the incylinder thermochemical conditions. According to [15], to get access to the thermochemical mixture properties holding the soot kinetics, a spray-model for modern Diesel engines based on the approach proposed in [13,20,22] was integrated into the DFM model to enrich the combustion scenario description given by the model. This spray model showed its potential for simulations of Diesel sprays, for single injection but also multiple injection strategies, for which injection-to-injection interactions cannot be neglected.…”

“…In the present work, a detailed phenomenological spray model for modern Diesel engines, as proposed in [13,20], was integrated into the DFM combustion model developed at IFPEN [21]. The implemented approach was thought to integrate as much as possible the specificities of the physics holding soot kinetics: this includes fuel properties and detailed thermochemical properties of the reactive mixture, but also the phenomenology related to sprays evolutions and combustion, and injection-to-injection interactions.…”

“…Based on the approach used in a previous study [23] and developed by Mauviot [18,37] and Dulbecco [26,27,44], we relate statistical variables to physical phenomena. Deriving the probabilistic definition of the mixture fraction variance, Equation (28) is obtained.…”

“…This approach makes use of the model developed in [18,26,27] for HCCI combustion, but in the present work only three species are considered: burned gas, unburned gas and fuel. The description of the combustion process is here also simplified by modeling the two combustion phases by their own sub-model.…”
