摘要：

The　numerical　simulation　of　wing-and-tube　evaporator　tube　side　in　organic　Rankine　cycle(ORC)system　is　carried　out　based　on　CFD　method,　the　accuracy　of　the　simulation　model　is　verified　based　on　experimental　data　from　the　engine-ORC　joint　system　test　bench,　and　the　flow　and　phase　change　heat　transfer　characteristics　of　the　working　fluid　R245fa　on　the　tube　side　are　analyzed.　By　changing　the　engine　speed,　evaporation　pressure　and　the　inlet　speed　of　the　pipe　side　working　fluid,　the　flow　and　heat　transfer　characteristics　of　the　working　fluid　under　different　working　conditions　are　compared　and　analyzed.　The　results　show　that　the　engine　speed,　evaporating　pressure　and　the　inlet　speed　of　working　fluid　in　the　tube　side　have　a　great　influence　on　the　evaporation　of　working　fluid.　The　engine　speed　has　little　effect　on　tube　side　inlet　and　outlet　pressure　drop.　The　evaporating　pressure　and　the　inlet　speed　of　working　fluid　have　the　great　influence　on　inlet　and　outlet　pressure　drop　in　the　tube　side.　©　2018,　Editorial　Board　of　Acta　Energiae　Solaris　Sinica.　All　right　reserved.
