Direct Numerical Simulation of Turbulent Combustion
Interdisziplinäres Zentrum für Wissenschaftliches Rechnen (IWR)
Direct numerical simulations of turbulent combustion can provide comprehensive
information about the basic interaction mechanisms of turbulence and
chemical reactions. Such information is needed for the development of enhanced
turbulence and turbulent combustion models. To reach this target, detailed
chemical reaction schemes and multicomponent diffusion models have to be
included in the DNS, leading to a demand of computational power that can only
be provided by the fastest supercomputers available.
Therefore, we developed a DNS code to be used on distributed memory parallel
computers with message passing communication. This code uses detailed transport,
thermodynamical and reaction models. The parallelization strategy is based on
a domain-decomposition in conjunction with dynamic load-balancing.
This code is utilized for an investigation of the fundamental processes apparent
in turbulent premixed and non-premixed flames.
