Three-dimensional　numerical　simulation　on　the　process　of　convective　heat　transfer　enhancement　of　a　heated　plate　in　a　channel　by　corona　windwasconducted　by　using　commercial　code　COMSOL　Multiphysics.　In　this　paper,　the　distribution　of　velocityand　electrical　forcein　the　channel　were　studied,　and　the　variation　of　convective　heat　transfer　coefficientunder　three　different　flow　conditions　were　investigated.　The　result　reveals　thatthe　electric　force　is　an　important　factor　affecting　the　enhancement　ofconvection　heat　transfer　by　corona　wind.　©　2015,　Science　Press.　All　right　reserved.
