本文提出了一种基于局部火焰速度概念的小火焰模型,以描述有限厚度的预混火焰,并定义了无量纲温度G。在前期的工作中,新的小火焰模型已被一维稳态预混火焰成功地验证。本文研究了三维逆流式甲烷-空气预混模型。局部火焰速度可以表示为φ 0 2 u u S S G G φ 0,其中标量0 G G φ表示小火焰模型中的火焰表面。考虑到拉伸效应,修正后的燃烧速度表达式为0 0 uuSSL λ S,其中uS小于未拉伸火焰的燃烧速度0 uS。新的火焰面模型的结果与原来的G-模型的结果进行了比较的速度和温度分布。通过CHEMKIN的GRI-Mech 3.0详细化学反应解决方案验证了上述结果。
The flamelet model based on the concept of local flame speed * S is newly developed to describe a premixed flame with a finite thickness when defining G as the non-dimensional temperature. In the previous work the new flamelet model was validated by 1-D steady premixed flame successfully. In this paper the model of 3-D counter flow premixed methane-air is investigated. The local flame speed can be proposed as   * 0 2 u u S S S G G    where the scalar 0 G G  represents the flame surface in the flamelet model. Considering the stretch effect the expression for the modified burning velocity is 0 0 u u u S S S L   where u S is smaller than the burning velocity of the unstretched flame 0 u S . The new flamelet model results are compared with the original G-model results in the velocity and the temperature profiles. The results are also validated by the detailed chemical reaction solution of GRI-Mech3.0 by CHEMKIN.
