We analyze the evolution of a diffusion flame in a turbulent mixing layer. The location of the flame-center is defined by the “stoichiometric” interface. Geometrical properties such as its surface-area, wrinkling and curvature are characterized using an accurate numerical level-set quadrature method. This allows to quantify flame-properties as well as turbulence modulation effects due to coupling between combustion and turbulent transport. We determine the active flame-region which is responsible for the main part of the chemical processing in the flame.
