| 摘 要： | 在一回路水分别从内侧和外侧加热二回路水的条件下，进行了竖直窄环隙流道强迫对流换热实验。结果表明，窄隙流道具有强化和抑制换热的双重作用，其换热特性与微槽道非常相似，而与普通流道显著不同．没有明显的层流区、过渡区和紊流区换热之分。 |

| Abstract: | Experiments have been carried out to investigate the forced convection heat transfer with water in narrow annulus which is heated from inside or outside by primary water. The results show that the narrow channel has a dual enhancement-suppression action on convection heat transfer. The performance of the heat transfer in narrow annulus is very similar to that in micro-channel, but is quite different from that in conventional channel. Heat transferring among laminar, transition and turbulent areas is with no obvious distinction. |
