| 摘 要： | 将每个计算单元分为燃料区、空气区和混合区3个区域,在火焰传播方向上又将每个区域分为已燃区和未燃区,建立了柴油机的三区相关火焰燃烧模型,利用该模型对超多喷孔柴油机和传统柴油机缸内燃烧过程进行三维数值模拟,不仅得到了与试验值相符的气缸压力、NOx和SOOT排放量等结果,而且获得了柴油机缸内混合气的浓度场、温度场、NOx质量...

| Abstract: | ECFM-3Z(Extended Coherent Flamelet Model-3 Zone) combustion model is established in diesel engine,in which each calculation cell is divided into 3 zone,unmixed air zone,mixed air and fuel zone,unmixed fuel zone,and in the flame propagation direction each zone is divided into unburned gases area and burned gases area.The combustion simulation in ultra-multi hole diesel engine and traditional diesel engine are made with the model.The simulated results include cylinder pressure,NOx quantity,SOOT quantity,which... |
