Measurement of Water Hammer Wave Speed in Coupled Field Petroleum Pipeline

液体管道的水击波速受流体压力、温度、分子结构、含气量及管线几何尺寸、管材等因素的影响,准确地确定管线的水击波速是一个相当困难的问题,通过实验测量水击波速是一个常用方法.管线水击波速的常用测量方法有波前法和周期法.综合运用波前法和周期法,设计了实验测量野战管线的水击波速,并将实验结果与笔者先前提出的水击波速计算公式的计算结果作了对比,验证了公式的有效性.

The determination of water hammer wave speed in liquid pipeline is quite a difficult problem because the wave speed depends on the liquid pressure, temperature, molecular structure, gas ratio, pipe dimension and material. A common way to determine wave speed is by experiment, which includes wave - front method and wave periods method. Combined with both wave - front method and wave periods method, experiments were designed to measure the wave speed in coupled field petroleum pipeline and compare is made between the experimental result and the calculated result. The result shows that the computational method proposed by the author is feasible.
