| 摘 要： | The experimental study on average holdup in multiphase pipelines with low loads of liquids was conducted on a large multiphase flow loop. The average holdup increased with increasing liquid load and decreased with increasing gas velocity, and also depended on the undulation of pipeline and flow patterns in the pipeline. The effects of eight dimensionless parameters on average holdup were seriated with grey relational degree analysis so as to find the most important factors affecting the average holdup in multiphase pipelines with low loads of liquids. An average holdup correlation based on low liquid loads was also developed and the correlation related the most important three factors including superficial gas velocity number (Ngw), superficial liquid velocity number (Nlw) and liquid Reynolds number (Rel) to the average holdup. Finally the correlation was tested with the field data and the result was satisfying.

| Abstract: | The experimental study on average holdup in multiphase pipelines with low loads of liquids was conducted on a large multiphase flow loop.The average holdup increased with increasing liquid load and decreased with increasing gas velocity, and also depended on the undulation of pipeline and flow patterns in the pipeline. The effects of eight dimensionless parameters on average holdup were seriated with grey relational degree analysis so as to find the most important factors affecting the average holdup in multiphase pipelines with low loads of liquids. An average holdup correlation based on low liquid loads was also developed and the correlation related the most important three factors including superficial gas velocity number(N_ gw), superficial liquid velocity number(N_ lw) and liquid Reynolds number(Re_l) to the average holdup.Finally the correlation was tested with the field data and the result was satisfying. |
