| 摘 要： | 融合一种新式燃烧理念的多孔介质发动机,能够实现发动机的均质、高效和稳定燃烧.为加深对两种形式多孔介质发动机燃用液体燃料着火特性的了解及探讨影响其各自压燃着火的因素,用改进的KIVA-3V对两种形式的多孔介质发动机燃用异辛烷的工作过程进行了模拟,并讨论了多孔介质初始温度、多孔介质结构对两种形式发动机压燃着火的影响.计算结果表明,压缩比一定时,多孔介质初始温度是决定两种形式多孔介质发动机能否实现压燃着火的重要因素;与永久性接触型发动机相比,在较低的多孔介质初始温度下,即可保证周期性接触型发动机实现压燃着火;多孔介质结构通过改变多孔介质内气固两相换热及弥散作用影响两种形式多孔介质发动机的压燃着火. |

| Abstract: | As a new combustion concept,homogeneous and stable combustion can be realized in porous medium(PM) engine equipped with a chemically inert porous medium.Toward a further understanding of the properties of PM engine,the working processes of two types of PM engine fueled with liquid fuel were simulated by using the improved CFD software KIVA-3V.The effects of initial PM temperature and PM structure characteristics on compression ignition of the two types of PM engine were also discussed.Computational results ... |
