Abstract: The density fluctuation correlation terms are introduced into modelling of a turbulent flame. A mathematical simulation of the density-scalar parameters fluctuation correlation terms (ρφ) is given in the calculation of combustion. The two transport equations for the density-velocity fluctuation correlation terms (pu and pv) are derived to solve the turbulence characteristics of a homogeneous gas flame and a heterogeneous pulverized coal flame. A further study has been made of the mutually interacting turbulent fluctuation and combustion process.
摘要: 针对湍流燃烧进行的模拟研究,本文较深入地探讨了湍流脉动与燃烧过程之间的相互作用关系,对密度-标量之间的脉动关联关系(?)提出了数学模化的表述形式,引入了以密度-速度脉动关联量为独立变量的两个输运方程与k-ε双方程模型一起作为对燃烧过程的湍流脉动待性的描述,并分别对气体均相燃烧和煤粉气流多相燃烧的全场作了数值求解.
