摘要：

A　simulation　model　of　fin-and-tube　evaporator　of　ORC　system　was　established　by　Fluent　software.　Then　the　flow　and　heat　transfer　characteristics　of　the　exhaust　in　the　evaporator　shell　side　were　obtained,　and　the　performance　of　finand-　tube　evaporator　of　ORC　system　was　analyzed　based　on　the　field　synergy　principle.　Subsequently,　the　influence　of　evaporator　of　ORC　system　on　diesel　engine　performance　was　studied.　A　simulation　model　of　the　engine　was　developed　based　on　GT-Power　under　various　operating　condition,　the　variation　tendency　of　engine　power,　torque　and　brake　specific　fuel　consumption　(BSFC)　were　obtained.　The　results　show　that　after　equipping　with　the　evaporator　of　ORC　system,　the　power　and　torque　of　diesel　engine　decreased　while　the　BSFC　increases.　With　the　increase　of　engine　speed,　the　power　loss,　the　torque　loss　and　the　BSFC　increment　of　engine　increase　gradually.　©　2016,　Science　Press.　All　right　reserved.
