| 摘 要： | 对一种场协同式周期性强化换热通道进行了数值模拟研究,考察了折流翅片不同角度、不同间距对通道换热特性的影响。计算结果表明,翅片倾角增大或间距缩小均有利于换热强化。强化效果随Re数的增大而愈加显著。

| Abstract: | A numerical study has been performed on the heat transfer in a parallel-plate channel in which the disturbance was periodically deployed by field synergy principle. The effects of the declining angle and the distance of disturbing fins on heat transfer were verified for different Reynolds numbers. The results show that increasing the declining angle or decreasing the fin distance in the studied range of parameter is helpful to enhance heat transfer. Further more, the enhancement effect is more obvious for high Reynolds number. |
