Detailed Simulations of Turbulent Flames Using Parallel Supercomputers

Direct numerical simulations (DNS) have become one of the most effective tools to investigate turbulent combustion. To further improve our knowledge about the fundamental interaction processes between turbulent transport and chemical reactions using DNS, it is necessary to include detailed chemical reaction schemes. This leads to an enormous demand of computational power, which can only be provided by the fastest supercomputers available. Therefore, we developed a code for the direct simulation of chemically reacting flows on massively parallel computers. We utilize this code to investigate the interaction of H₂/O₂/N₂ flames with decaying turbulence.
