摘要: A model is described which permits the incorporation of complex hydrocarbon chemistry into a detailed flow field prediction for turbulent nonpremixed combustion. The microscopic element in the turbulent ensemble is taken to be a stretched laminar flamelet, drawn from a library of such flamelets in which the extent of local stretching is characterized by χ≡ 2D (∂ ξ∂ xk)(∂ ξ∂ xk). This quantity, which varies with position in the laminar flamelet, is evaluated at the location of the peak temperature. The mean turbulent scalar dissipation …
