摘要
以甲烷/空气的湍流射流扩散燃烧为基础,利用-双方程模型和混合分数方程模型的耦合,依据湍流扩散燃烧中整个区域的混合分数场,给出火焰面形状尺度随过量空气系数的变化规律。模拟结果表明混合分数方程确定火焰面的位置是行之有效的方法。
Based on the turbulent shoot non-premixed combustion of methane/air, using k-ε double equation modle and laminar flamelet model to coupling, and according to the mix-fiaction of turbulent non-premixed combustion to bring up the regularity of blaze figure along with excessive air coefficient. The result of the simulation shows that mixture fraction equation is an effective way.
