【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。更多还原

【Abstract】 Basedon the turbulentshoot non-premixed combustion ofmethane/air, using doubleequation modle and laminarflameletmodel to coupling, and according to the mix-fraction of turbulent non-premixed combustion to bring up the regularity of blaze figure along with ex- cessive air coefficient. The result of the simulation shows that mixture fraction equation is an effective way.更多还原
