乙醇/柴油混合燃料燃烧过程数值模拟
Numerical Simulation on High Pressure Common Rail Diesel Engine Uses Diesel-ethanol Mixed Fuel
摘要
Abstract
Using CFD simulation tool FIRE to simulate the combustion process that a high pressure common rail diesel engine use diesel-ethanol mixed fuel , and a 3 D simulation model was established and validated .using the established model to study the combustion characteristic of the mixed fuel ,calculating the influence of the mixing ratio of ethanol on the mean pressure in the cylinder ,accumulated heat release and rate of heat release and so on;various performances that the diesel engine uses mixed fuel were calculated .The result shows that :in high load condition , the low cetane number , high latent heat of vaporization and the proportion of oxygen of the ethanol have great effect on the mean pressure in the cylinder and the heat release rate ,the diesel engine has the best dynamic and economic performance with E 10 mixed fu-el .关键词
