| 摘 要： | 基于2种节距比管束间的不同流型的压差波动信号，采用递归定量分析法研究了泡状流、间歇流、雾状流3种典型流型及过渡流型的动力学特性。研究结果表明：泡状流在递归图上表现为孤立点状结构，间歇流递归图兼顾点状和块状结构，具有较强的混沌特性，雾状流沿对角线纹理发育好，周期性突出。压差信号的递归纹理结构清晰地演化了其动力学特性，且递归特征量随气相折算流速变化明显，为两相流流型机理的研究提供新思路。

| Abstract: | Based on the differential pressure fluctuating signals of the gas-liquid two phase flow measured in two pitch tube bundles,the recurrence quantification analysis method was used to study the dynamic characteristics of differential pressure fluctuating signals of bubbly flow,intermittent flow,mist flow and transition flow patterns.The research indicated isolated points texture appeared on recurrence plot for the bubbly flow.Both dispersed points texture and massive texture appeared on recurrence plot for the... |
