两相流管线振动分析

对于两相流引起的管线振动,首先必须对管线内流体进行分析。该文给出了流体振动频率的计算方法。即:先用流型图判断流体流型,然后分析各流型中最易引起管线振动的段塞流。若为段塞流,应再进一步分析并计算段塞流的频率。

Analysis on vibration of two phase stream pipeline

For pipeline vibration due to two phase stream, analysis for pipeline fluid is first must be earned out. The calculation method of fluid vibration frequency is given in the article, that means: first determining fluid pattern using flow pattern chart, then analyzing section plugging stream in each flow pattern which is easy to cause pipeline vibration, if so, further analyzing and calculating the frequency of the section plugging stream.
