采用二维数值模拟方法研究了层流逆流喷雾火焰中液滴尺寸对碳烟生成行为的影响。正癸烷（C10H22）用作液体燃料，并且液滴运动通过拉格朗日方法计算。燃烧放热采用一步全局反应。采用基于动力学的碳烟生成模型和火焰面模型预测碳烟生成。辐射考虑使用离散纵坐标法。结果表明，喷雾火焰中扩散燃烧和预混燃烧共存，碳烟主要形成于喷雾扩散火焰区。液滴尺寸对碳烟的形成行为有很大的影响。碳烟体积分数随液滴尺寸的增大而增大。
A two-dimensional numerical simulation is applied to spray flames formed in a laminar counterflow, and the effect of droplet size on soot formation behavior is investigated in detail. N-decane (C10H22) is used as a liquid fuel, and the droplet motion is calculated by the Lagrangian method. A one-step global reaction is employed for the combustion heat release. A kinetically based soot formation model with flamelet model is employed to predict the soot formation. Radiation is taken into account using the discrete ordinate method. The results showed that the diffusion and premixed combustion co-exist in the spray flame and the soot is mainly formed in the spray diffusion flame region. The soot formation behavior is strongly affected by the droplet size. The soot volume fraction increases with the droplet size.
