摘要：

To　research　the　influence　of　the　ink　viscosity　on　the　ink　flow　characteristics　in　microscale　during　the　printing　process,　the　ink　viscosity　on　the　ink　flow　characteristics　was　first　analyzed　in　theory.　Then,　the　effect　of　the　viscosity　on　the　ink　flow　characteristics　was　simulated　in　conditions　of　slip　and　no　slip　using　FLUENT　that　is　professional　fluid　simulation　software.　Results　show　that　under　two　conditions,　the　maximum　pressure　increases　with　the　increase　of　the　viscosity.　Under　no　slip　condition,　the　viscosity　has　no　effect　on　the　ink　velocity.　However,　under　the　slip　condition,　with　the　increase　of　the　viscosity,　the　ink　velocity　increases　first　and　then　decreases,　however,　remains　unchanged　fianlly.　By　contrast,　considering　the　slip　or　not,　it　has　great　influence　on　the　maximum　velocity　of　ink.　Therefore,　it　is　necessary　to　consider　the　slip　when　analyzing　the　influence　of　the　viscosity　on　the　ink　flow　characteristics.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
