The DI-SRM accounts for detailed chemistry, in-homogeneities in the combustion chamber and turbulence-chemistry interactions. The existing implementation [1] was extended with a framework facilitating the use of tabulated soot source terms. The implementation allows now for using soot source terms provided by an online chemistry calculation, and for the use of a pre-calculated flamelet soot source term library. Diesel engine calculations were performed using the same detailed kinetic soot model in both configurations. The chemical mechanism for n-heptane used in this work is taken from Zeuch et al. [2] and consists of 121 species and 973 reactions including PAH and thermal NO chemistry. The engine case presented in [1] is used also for this work. The case is a single-injection part-load passenger car Diesel engine with 27 \% EGR fueled with regular Diesel fuel. The two different approaches are analyzed and a detailed comparison is presented for the different soot processes globally and in the mixture fraction space. The contribution of the work presented in this paper is that a method which allows for a direct comparison of soot source terms - calculated online or retrieved from a flamelet table - without any change in the simulation setup has been developed within the SRM framework. It is a unique tool for model development. Our analysis supports our previous conclusion [1] that flamelet soot source terms libraries can be used for multi-dimensional modeling of soot formation in Diesel engines.}, language = {en} } @inproceedings{MatriscianoSeidelKlaueretal., author = {Matrisciano, Andrea and Seidel, Lars and Klauer, Christian and Lehtiniemi, Harry and Mauß, Fabian}, title = {An a priori thermodynamic data analysis based chemical lumping method for the reduction of large and multi-component chemical kinetic mechanisms}, series = {5th International Workshop on Model Reduction in Reacting Flows, L{\"u}bbenau, 2015}, booktitle = {5th International Workshop on Model Reduction in Reacting Flows, L{\"u}bbenau, 2015}, pages = {2}, abstract = {A chemical species lumping approach for reduction of large hydrocarbons and oxygenated fuels is presented.
