条件矩模型对CH4-空气扩散燃烧及其NOx生成的数值模拟
摘要
采用Bilger提出的条件矩模型
在考虑辐射热损失的情况下对CH4-空气湍流射流扩散燃烧及其NOx生成进行了数值模拟 .对于湍流流动和混合分数场采用k -ε - f - g模型
Conditional moment closure(CMC) model proposed by Bilger is used for simulation of CH 4-Air diffusion combustion and its NO x formation
taking into account a radiant heat losses in this paper.Simulation is carried out by using k-ε-f-g model for velocity and mixed fractions
and a parabolic equation of conditional moment closure (CMC) for component concentration.A comparison of the prediction and experimental data demonstrates that CMC has good performance in the prediction of the fields of velocity
temperature and main component(CH 4
CO 2) concentration
the prediction of NO concentration is in agreement with in experimental data with acceptable departure.
