| 摘 要： | 对迪恩涡的强化传热作用进行了初步的实验研究，发现在迪恩涡的作用下，90°弯管的传热系数明显高于直管；弯管的阻力损失在层流区略高于直管，但是在过渡区之后便开始低于直管的阻力损失。迪恩涡强化传热技术在提高传热系数、降低阻力损失方面有着极大的潜力，是一种节能的强化传热技术。

| Abstract: | Experimental study had been carried out whose results indicated that the heat transfer coefficient of the 90°curved turned out to be much higher than that of the straight tube,with a relatively low pressure drop after the transitional region.Dean vortices heat transfer enhancement technology had a great potential in increasing the heat transfer coefficient and lowering the resistance loss,thus it is worth studying on. |

| Keywords: | heat transfer enhancement technology dean vortices convection effect heat transfer coefficient pressure drop |
