Abstract: 中文导读:本文综述了空管道和置障管道内湍流预混燃烧的大涡模拟研究现状。从模型开发的角度,本文综合分析了重要的亚格子涡粘模型和亚格子燃烧模型的发展历程及其适用性。大涡模拟方法也被用来将流动及燃烧模型有机结合去再现现实生活中管道爆燃、爆轰以及爆燃转爆轰(DDT)现象。文章中所呈现的模型及其应用可以引导读者理解大涡模拟在管道爆炸方面的研究进展及其不足之处。

Abstract: 中文导读—本文在40 kW规模的实验炉中研究了MILD(温和与极度低氧稀释)燃烧(MILDC)与具有可见火焰的传统燃烧(TC)中的氮氧化物(NO)的形成和排放特性。在同一炉膛中持续开展了两种燃烧条件下的天然气燃烧实验,功率固定为19kW,当量比为0.86。为了解释两种燃烧中所测得的炉温和烟气中NO排放的差异,对TC和MILDC进行了数值模拟。文中展示了NO排放(XNO)在不同炉壁温度(Tw)...

Abstract: 中文导读—使用0号柴油和杨木粉,研究了油粉比(即柴油质量与木粉质量之比)对柴油浸润木粉燃烧特性的影响。油粉比设置为0、0.5、1.0、1.5和2.0,实验中测量和分析了火焰行为、温度分布、质量损失率和一氧化碳浓度。结果表明,由于蒸发和毛细力的耦合作用,与纯木粉(燃点在280℃以上)和纯柴油(闪点在107℃以上)相比,柴油浸润了的木粉的燃点显著下降(小于4℃)。在燃烧初期,柴油在毛细力的作用下...
