Abstract

The Eddy Dissipation Concept (EDC) is a well working concept for turbulent reacting flows, which depicts the influence of chemical reactions as well as turbulence. The problem when using detailed chemical mechanisms - necessary for more information about radical species and pollutants - is the vastly increased computational demand. Operator splitting and in situ adaptive tabulation (ISAT) can be a way to reduce the computational effort and improve the application of detailed chemical mechanisms with the EDC. Two operator splitting mechanisms are presented and used for the simulation of Sandia Flame D. The computational time can be decreased and the results fit well to the experimental results.
