全状态两相湍流燃烧模型及其检验

Full status two phase turbulent combustion model

在欧拉-拉氏体系中,在传统点源两相湍流燃烧模型(TM)中考虑液滴带火燃烧状态,提出全状态两相湍流燃烧模型(FSM),并用甲醇-空气两相湍流射流火焰实验数据对两种模型进行检验,对比结果表明:FSM模型能够给出平均温度的双峰分布,得到更合理的预报结果.

In Euler-Lagrange frame,the individual droplet burning behavior was added into the traditional point source two phase turbulent combustion model（TM）,and then a full status two phase turbulent combustion model（FSM） was presented.The two kinds of two phase turbulent combustion models were tested by a set of methanol air two phase turbulent spray jet flame experimental data.The comparison results between the computational prediction results and the experimental data show that the FSM model can give two peaks in the averaged temperature profile,as well as more reasonable predictions.
