摘要

摘要: 针对不稳定流动（脉动流）条件下的实时阻力特性进行了实验研究。研究表明：脉动流造成了摩擦压降特性的改变，摩擦压降随流动波动而波动，且二者存在相位差。分析可知，加速度对摩擦压降产生较大影响，相同大小的流速和加速度下，加速度方向不同时，摩擦压降也不同，加速度为正时，摩擦压降较大，加速度为负时，摩擦压降较小，加速度为0时，摩擦压降为唯一值。在理论分析的基础上，拟合了适用于脉动流条件下的实时摩擦压降计算关系式，拟合结果和实验结果符合良好。

Abstract: Experimental studies on single-phase real time flow resistance characteristics under unsteady flow condition were carried out. The experimental phenomena show fluctuation changes friction pressure drop characteristics. The friction pressure drop fluctuates with fluctuation flow and there is phase difference between two fluctuation signals. Based on analysis, such conclusions can be achieved that the acceleration may strongly influenced friction pressure drop, and with the same flow rate, the friction pressure drop is different with different directions of acceleration. When the direction of acceleration is same as that of flow rate, the friction pressure drop is large, when the acceleration is opposite with flow rate, the friction pressure drop is small. Based on theoretical analysis, an empirical correlation was obtained to calculate real time friction pressure drop of fluctuation conditions and calculated results fit well with experimental data.
