A cyclonic burner operating under moderate or intense low-oxygen dilution (MILD) conditions is simulated using a perfectly stirred reactor (PSR) incorporated within a tabulated chemistry approach. A presumed joint probability density function method is used with appropriate submodels for the turbulence–chemistry interaction. Non-adiabatic effects are included in the PSR calculation to take into account the effects of non-negligible wall heat loss in the burner. Five different operating conditions are investigated, and the computed mean temperatures agree well with measurements. A substantial improvement is observed when the non-adiabatic PSR is used, highlighting the importance of heat transfer effects for burner configurations involving internal exhaust gas recirculation. Furthermore, enhanced reaction homogeneity is observed in this cyclonic configuration for the globally lean case, leading to a more spatially uniform temperature variation with MILD combustion.

使用非绝热列表化学对中度或强烈低氧稀释条件下旋风燃烧器的数值研究

使用包含在列表化学方法中的完全搅拌反应器（PSR），模拟在中等或强烈的低氧稀释（MILD）条件下运行的旋风燃烧器。假定的联合概率密度函数方法与湍流-化学相互作用的适当子模型一起使用。PSR计算中包括非绝热效应，以考虑到燃烧器中壁热量损失不可忽略的影响。研究了五种不同的工作条件，计算出的平均温度与测量值吻合得很好。当使用非绝热PSR时，观察到了实质性的改进，突出了传热效果对涉及内部废气再循环的燃烧器配置的重要性。此外，
