摘要:
采用CHEMKIN中的反射激波管模型,模拟了生物柴油的燃烧,探讨了不同当量比和EGR率对生物柴油的碳烟前驱体多环芳香烃中的苯、萘、菲、芘的影响.研究表明:当量比由1.0,1.7到2.1逐渐增大,苯、萘、菲、芘的摩尔分数变小,抑制多环芳香烃的形成,减少碳烟;前期EGR率为0,5％,10％,20％和40％时苯的曲线几乎重合,4μs后EGR率为40％;萘、菲、芘随EGR率增大呈增大趋势.
Abstract:
The reflected shock using CHEMKIN model to simulate biodiesel combustion, analyze the effects ofdifferent equivalence ratio and EGR rate on the biodiesel soot precursor polyeyelic aromatic hydrocarbons onbenzene , naphthalene, phenanthrene and pyrene. The results showed that; benzene, naphthalene, phenan.threne, pyrene mole fraction decreased with the increase of equivalence ratio form 1. 0 , 1. 7to 2. 1 , inhibitedthe formation of polyeyclic aromatic hydrocarbons, decreased the soot ,ECR rate of 0 ,0 ,5% , 10% , 20% and40% benzene curves almost coincide in the prophase, 40% EGR rate higher after 4 us, naphthalene, phe.nanthrene , pyrene increased with the increase of EGR rate.
