流动不稳定性 meaning in English

flow instability

In this dissertation , the experimental study of rolling condition on two - phase flow instabilities of the forced - single - tube circulation system was carried out . furthermore , based on the d - partition method and the hypothesis of drift flow model , given some conservative equation , using the perturbation method the response of the pressure drop of the tube to the inlet flow rate perturbation was analyzed both in rolling condition and in normal upright position
本文主要通过实验对摇摆条件对单管强迫循环中汽液两相流动不稳定性的影响，同时在d分区法的前提下，在两相区基于漂移流模型，一定的守恒条件下，在摇摆和不摇摆工况中用线性小扰动法对实验段的压降对入口流速的扰动的响应进行了分析。
