摘要：

Direct numerical simulations (DNS) have become one of the most important tools to study turbulent combustion Computation time is still a main limiting factor for the DNS of reacting pouts, especially in the case of using detailed chemical mechanisms. The computation of the chemical source terms is one of the most time-consuming parts in such DNS. An adaptive evaluation of the chemical source terms is used in the presented DNS of turbulent diffusion, flames. This leads to a decrease of the time needed for this part of the computation by more than a factor of five without any significant loss of accuracy of the results.
