| 摘 要： | 介绍了空气和高温燃气在带内翅片园管内流动时，流动阻力实验的研究结果。全部实验数据整理成ξ＝ｆ（Ｒｅ）的准则方程，除两个实验状态的偏差为±１０．２％外，其它的实验点，按我们所综合的阻力公式的计算值与实测值之间的偏差大都小于５％。

AN EXPERIMENTAL INVESTIGATION ON FLOW DRAG IN TUBE WITH INNER FANS |
| |
| Abstract: | Abstract The experimental investigation on flow drag of the air or high temperture gas flows passing through the tube with inner fans.The range of air temperature is from 287 2K to 259 1K and that of the gas tempreature is from 347 3K to 499 7K.The velocity of the flow varies from 7 3 to 41 7m/s.A correlative equation between Renolds number and drage coefficient is formulated,based on all test data.The results calculated with the correlative equation are in good agreement with the data of tests. |
