| 摘 要： | 为了探索混输管线气量瞬变过程压力、压差的变化规律，在长378 m、内径0.08 m的水平不锈钢试验环道上利用空气和水进行了段塞流气量增加瞬变试验研究.试验采用压力变送器测量压力信号，将相邻两压力信号相减（上游减下游）得到压差信号.根据试验结果，分析了气量增加瞬变过程中压力、压差的变化规律，从概率密度分布和功率谱密度两方面对压力、压差信号进行了统计分析，完善了气量增加瞬变过程中压力过增值的回归方程式.

| Abstract: | In order to find the characteristics of gas flowrate increasing transient under the slug flow regime,a statistical investigation was carried out in a 378 m long, 80 mm i.d. stainless steel pipeline. Air and water were used as test fluids and responses to change of gas flowrate were measured by using a series of pressure transducers. Differential pressure signal was obtained by subtracting downstream pressure signal from upstream pressure signal.According to the test results, the development trends and statistical characteristics of pressure and differential pressure along the pipe during the transient process of gas flowrate increasing was analyzed.An equation for the calculation of pressure overshoot was proposed for this transient process. |
