输水(油)管道入口整流效应的试验研究

Effectiveness of Flow Straitening at the Inlet of Water/Oil Supply Facility

供水 (油 )设备的入口形成的旋涡 ,会造成较强的脉动运动 ,从而影响流动品质 ,在一定程度上降低了输水效率 .在循环水系统中 ,脉动速度给循环水泵的工作状态带来不利 ,增加振动和噪音 .为此 ,笔者设计出一组整流器 ,旨在削减旋涡对输水的影响 ,并在一简易的透明输水管道中进行流态观察和测量 .试验结果表明 :本方法可以疏理流态 ,使脉动速度有较明显的减小 .在本实验的雷诺数范围内 。

The Vortex formed at the inlet of water/oil supply facility causes an intensive pulsating velocity, directly affecting the flow quality, and hence causing the cycle pump vibrate in the circulatory pipe system. A vortex breaker designed by the authors is introduced. Experimental results show that this methord can both straiten the streamlines and slightly decrease the total flow drag.
