摘要: To study the influence of a turbulent diffusion flame on transport phenomena to reacting surface we used previously designed simulation apparatus. Velocity, temperature and turbulence profiles were obtained by laser doppler velocimetry compensated thermocouples measurements. Stable species chromatographic analysis samples withdrawn from reactive zone. We developed q -e model probabilistic combustion model. Agreement between theory experiment is particularly good for mean velocity values, heat flux wall, mass burning rates transfer numbers. The overshoot also predicted satisfactorily related increase pressure gradient. For intensity, agreement below flame, above it discrepancy low-frequency oscillations due transverse perturbation. Finally, this can be rate solid materials.
