DNSを用いた乱流予混合火炎近傍の温度場による熱的影響の検討

Turbulent premixed flames are heat release phenomena in the turbulent flow with premixed fuel and oxidiser. Turbulent premixed flames form the temperature field and are affected by the interaction between flow and heat. This study focused the temperature field adjacent to the flames and considered the effect of the interaction between flow and heat on the flames using DNS (Direct numerical simulation). In the development of planar flame in the turbulence field, the results show that spread of the flame zone leads to enhancement of the effect of turbulence field on the isosurface of temperature upstream of flames, and that the distribution of heat conduction does not deviate from the isosurface of temperature in the case of small wrinkles on the isosurface of temperature.
