Applying ILMD technique with time scaling for CFD simulation of diesel engine

Detailed mechanisms describing ignition, flame propagation and pollutant formation typically involve several hundred species and elementary reactions, prohibiting their use in practical three-dimensional engine simulations. Conventionally reduced mechanisms often fail to predict minor radicals and pollutant precursors. The ILDM-method is an...

Implementation of ILDMs based on a Representation in Generalized Coordinates

The usage of detailed chemical kinetics for the mathematical modeling of combustion processes is desirable, but leads to a high computational effort. In the present work one of the methods of simplification of chemical kinetics - Intrinsic low-dimensional manifolds (ILDMs) is considered. Whereas in most CFD applications ILDMs are calculated in...
