摘要
本文使用"CO相对燃烧速率"的概念和通用的"有效影响参数转化方程",将带有气相反应速率无穷快假设的移动火焰锋面(MFF)模型成功地扩展应用到有限气相反应速率条件的计算中。对于多组不同有限气相反应速率、以及不同粒径的碳粒燃烧计算,MFF模型扩展应用的预报结果都与严格连续膜模型符合较好,碳粒着火温度的预报也更为准确。
In this article,the MFF model with the assumption of infinitely-fast homogenous reaction, was successfully extended to be used to the finite-rate cases,applying the concept of ＇characteristic combustion rate of CO relative to its generation＇ and a universal ＇effectiveness-transforming formula＇. The predictions by the amended MFF model agree well with those by the rigid continuous-film model, no matter what kinetics of the homogenous reaction are taken,and no matter what particle diameters are.The predictions of particle ignition temperature are more accurate,too.
