基于近年发展的多维条件映射(MMC)小尺度混合模型及化学反应-扩散流形(REDIM)化学反应机理简化技术,提出一新型燃烧模型,将REDIM技术提供的“多维”流形与MMC技术所采用的“多维”条件映射概念有机结合,并将此燃烧模型应用到有限体积-拉格朗日粒子联合算法中。为了对新模型的性能进行初步验证,对一维的预混合层流火焰进行了数值计算,获得了该火焰的传播速度、厚度及组分的分布情况,并与基准的直接数值计算结果进行了对比研究,两者吻合良好。
Based on the multi-dimensional condition mapping (MMC) small-scale hybrid model developed in recent years and the simplified chemical reaction-diffusion manifold (REDIM) chemical reaction mechanism, a new combustion model is proposed to combine the “multidimensional” The concept of “multidimensional” condition mapping adopted by technology is combined organically, and the combustion model is applied to the finite volume - Lagrangian particle combination algorithm. In order to verify the performance of the new model, the one-dimensional pre-mixed laminar flow flame was numerically calculated, and the propagation velocity, thickness and composition of the flame were obtained. The results were compared with the direct numerical results Comparative study, both agree well.
