An　enhancement　surface　of　heat　transfer　was　developed　based　on　the　field　synergy　principle.　The　characteristics　of　turbulent　heat　transfer　and　flow　were　studied　experimentally.　The　effects　of　fin　angle,　channel　height,　and　Reynolds　number　were　investigated.　The　assessment　under　the　constraint　of　identical　pump　power　consumption　revealed　that　in　the　fin　angle　range　of　β　=　0-23.2°　the　enhancement　ratio　increased　monotonically　with　increasing　β,　but　decreased　with　increasing　Reynolds　number.　For　a　fixed　fin　angle,　higher　ducts　showed　lower　power　consumption　and　higher　heat　transfer.
