流体在固体壁面流动的边界问题

Bundary Problem between Solid Surface and Flowing Liquid

指出由气体分子运动论所得到的判别“壁面滑移”的Knudsen准则对液体不适合,有必要对液体壁面边界问题作深入的理论和实验探讨。提出了通过管道内壁改性减阻,降低能耗,提高管道输油效率的研究方向。

It is pointed out in the paper that knudsen criterion got according to gas molecular movement to define 'Surface Sliding' is not suitable for liquid, therefore it is necessary to do further theoretical and practical research about the bundary problem between solid surface and flowing liquid. It is also put forward that the reduction of energy consumption can be realized by changing pipeline's internal wall performance so as to increase flow rate.
