基于湍流氢气。空气扩散火焰,对磷酸三甲酯(TMP,(CH3O)3PO)的火焰抑制效果进行了数值研究,使用一阶条件矩封闭模型作为湍流燃烧子模型.为了研究氢原子浓度减小的机理,对其相关的重要基元反应进行了分析。最后根据所获得的数值结果及火焰燃烧结构和抑制效果,对TMP的灭火特性进行了详细的讨论分析.
This study has been conducted to investigate computationally the flame inhibition effect of trimethyl phosphate (TMP, (CH30) 3PO) in the frame of turbulent diffusion hydrogen-air jet flame. The first-order conditional moment closure (CMC) is used as turbulence combustion sub-model. To identify the key reactions responsible for the observed reduction in H-atom, an analysis of individual reaction is presented. Based on the numerical results, a detailed discussion is given on the inhibition properties of TMP in terms of flame structure and inhibition effectiveness.
