The 4th Workshop of the Engine Combustion Network (ECN) was held September 5-6, 2015 in Kyoto, Japan. This manuscript presents a summary of the progress in experiments and modeling among ECN contributors leading to a better understanding of soot formation under the ECN “Spray A” configuration and some parametric variants. Relevant published and unpublished work from prior ECN workshops is reviewed. Experiments measuring soot particle size and morphology, soot volume fraction (fv), and transient soot mass have been conducted at various international institutions providing target data for improvements to computational models. Multiple modeling contributions using both the Reynolds Averaged Navier-Stokes (RANS) Equations approach and the Large-Eddy Simulation (LES) approach have been submitted. Among these, various chemical mechanisms, soot models, and turbulence-chemistry interaction (TCI) methodologies have been considered

“…4 summarizes the operation of the TRIF combustion model, illustrating the mutual interactions between the CFD, flamelets domains and chemistry table. Further details about the RIF model implementation in Lib-ICE can be found in [3,19,20]. Despite using tabulated reaction rates, TRIF simulations will have higher computational costs compared to TWM or TPPDF due to the need to perform on-line the integration of Eq.…”

“…For each flamelet marker M j , a transport equation is solved including spray evaporation source term only for a specified interval of the injection duration [3].

“…To identify the most promising solutions, effects of combustion chamber design, injection strategy, EGR and compression ratio must be studied simultaneously and for this reason robust, accurate and fast approaches are required. In the last decade, most of the efforts were focused on incorporating detailed kinetics in Diesel spray combustion simulations with or without turbulence-chemistry interaction to predict ignition delay, flame structure (lift-off and PAH) and the main pollutant emissions [3,4,5,6]. However, to accurately describe the oxidation of complex fuels including the formation of soot precursors, a large number of species and reactions is necessary with a consequent increase of computational time, since ODE stiff solvers are employed to compute the chemical reaction rates and as many transport equations as the number of involved species have to be solved.…”

Computational fluid dynamics represents a useful tool to support the design and development of Heavy Duty Engines, making possible to test the effects of injection strategies and combustion chamber design for a wide range of operating conditions. Predictive models are required to ensure accurate estimations of heat release and the main pollutant emissions within a limited amount of time. For this reason, both detailed chemistry and turbulence chemistry interaction need to be included. In this work, the authors intend to apply combustion models based on tabulated kinetics for the prediction of Diesel combustion in Heavy Duty Engines. Four different approaches were considered: wellmixed model, presumed PDF, representative interactive flamelets and flamelet progress variable. Tabulated kinetics was also used for the estimation of N O x emissions. The proposed numerical methodology was implemented into the Lib-ICE code, based on the OpenFOAM R technology, and validated against experimental data from a light-duty FPT engine. Ten points were considered at different loads and speeds where the engine operates under both conventional Diesel combustion and PCCI mode. A detailed comparison between computed and experimental data was performed in terms of in-cylinder pressure and NO x emissions.
