The reduction process is kept time efficient by only using 0D and 1D reactors. To account for the expansion phase in internal combustion engines a stochastic engine tool is used to validate the reduction steps. 5th International Workshop on Model Reduction in Reacting Flows, Lübbenau, 2015 www.modelreduction.net http://modelreduction.net/wp-content/uploads/2015/07/5th_IWMRRF_2015.pdf an der BTU erstellt / created at BTU Lars Seidel Fabian Mauß Christian Klauer Michal Pasternak Andrea Matrisciano Corinna Netzer Martin Hilbig Fabian Mauß eng uncontrolled Combustion, Mechanism Reduction LS Thermodynamik / Thermische Verfahrenstechnik FG Thermodynamik / Thermische Verfahrenstechnik
