中文摘要：

本文以空气为介质,在Re=200时下表面布置有三角形翅对和矩形翅对的槽道内的层流的等热流边界条件下的对流换热进行了数值分析;对速度梯度与速度在二次流存在时对流换热机理的贡献进行了详细地分析。研究发现,布置有矩形翅对的涡产生器产生的涡较三角形翅对更剧烈,速度梯度与速度对传热的贡献在这时也有明显的不同。

英文摘要：

With air as the medium in this paper,a numerical method is used to study the convective heat transfer in a channel mounted with rectangular winglet pair（RWP） and delta winglet pair（DWP） on the bottom wall.Reynolds number is 200.When the convection of heat flux equation is used,conducted a detailed analysis of the combination of heat flux with velocity gradient and velocity with heat flux gradient contribute the heat transfer enhancement.The results show that Vortex of mounted with RWP is more intense than mounted DWP.Mounted RWP have a better enhanced heat transfer than mounted DWP.But the compression of resistance coefficient and enhance heat transfer,DWP performance better heat flux with velocity gradient and velocity with heat flux gradient contribute the heat transfer enhancement are also significant differences.
