The　dynamic　viscosity　modeling　of　nine　oxygenated　fuels　(diethyl　ether,　diisopropyl　ether,　dibutyl　ether,　dimethoxymethane,　1,2-dimethoxyethane,　diethylene　glycol　dimethyl　ether,　dimethyl　carbonate,　diethyl　carbonate　and　diethyl　adipate)　was　presented　with　several　representative　models.　The　evaluated　viscosity　models　range　from　empirical　model,　semi-empirical　model　such　as　residual　viscosity,　to　models　with　strong　physical　background　such　as　hard-sphere　scheme　and　free-volume　viscosity　model.　The　evaluation　results　indicated　that　the　Assael　five　parameters　model　has　the　best　performance　for　the　studied　fluid.　Similar　to　the　hard-sphere,　free-volume　model　has　a　physical　and　theoretical　background　and　related　to　characteristic　parameters,　making　this　model　totally　predictive　for　the　dense　fluid.　(c)　2012　Elsevier　Ltd.　All　rights　reserved.
