摘要：

The scalar structure of the overfire (fuel-lean) region of sooting turbulent diffusion flames was investigated considering ethylene and acetylene burning in air. Measurements and predictions are reported of the mean concentrations of major gas species and mean soot volume fractions. Predictions were based on the conserved-scalar formalism in conjunction with the laminar flamelet approximation. The comparison between predictions and measurements was encouraging, suggesting that state relationships for major gas species, found in laminar diffusion flames, were preserved in the overfire region of the turbulent flames.
