摘要

化石燃料燃烧产生的煤烟影响气候和人类健康,乙烯层流火焰是煤烟产生的重要研究对象。通过对比实验数据验证了数值计算模型的准确性后,比较分析了入口流量和燃料流量组成工况的变化对烟灰产生的影响。计算结果与实验数据在分布趋势上是一致的。计算得到的峰值积分烟气体积分数的偏差仅为5%。在本研究设定的操作条件下,增加伴随空气的体积流速将增加乙烯层流扩散火焰产生的烟灰的体积分数。增加燃料体积流量将首先增加,然后减少烟灰的体积分数。

Numerical Simulation of Soot Formation in Ethylene Laminar Diffusion Flame
The soot produced by fossil fuel combustion affects climate and human health, and the ethylene laminar flame is a crucial research object of soot generation. After verifying the accuracy of the numerical calculation model by comparing experimental data, the impact of changes in inlet flow rate and fuel flow composition operating conditions on the generation of soot were compared and analyzed. The calculated results obtained are consistent with the experimental data in terms of distribution trend. The deviation of the calculated peak integral smoke volume fraction is only 5%. Under the operating conditions set in this study, increasing the volume flow rate of the accompanying air will increase the volume fraction of soot generated by the ethylene laminar diffusion flame. Increasing the fuel volume flow rate will first increase and then decrease the volume fraction of soot.
