Combustion processes are governed by a strong coupling of chemical kinetics, molecular transport processes and flow. Mathematical modeling is complicated by the existence of scaling problems (time-, velocity-and length scales). In order to allow a reliable numerical simulation of practical combustion systems, models have to be devised which do not neglect or over-simplify the underlying physical and chemical processes. In this paper hierarchical modeling concepts are presented which allow the development of realistic and reliable modeling tools based on information from detailed simulations.
