| 摘 要： | 本文采用两种不同的处理液处理玻璃管道内壁，改变管内壁与流体水之间的粘附功，研究了粘附功对光滑直管内流动阻力的影响。试验结果表明，在管壁与液体间的粘附功小于液体的内聚功条件下，当液体的雷诺数大于临界雷诺数时可显现明显的内流减阻效果。

| Abstract: | The influence of adhesive work between inwall of conduit and water upon flow resistance in smooth straight conduit was investigated by treating the inwall of glass conduit with two different treating liquids to change the adhesive work. The result shows that if Reynolds number of liquid flow in conduit is greater than the critical Reynolds number, an apparent drag reduction can be obtained under the condition that the adhesive work between inwall and liquid is smaller than the cohesive work of liquid. |
