| 摘 要： | 以空气和水为工质,采用双平行电导探针,在水平多相流环道(d=50.00mm)中研究了段塞流持液率与压力波动的关系以及折算气速、折算液速变化对持液率的影响,并将持液率的试验值与预测模型进行了比较.结果表明:持液率波动能更真实地反映段塞流动特性,可以用来确定液塞频率;增加折算气速时,液塞持液率减小;增加折算液速时,持液率增大.

| Abstract: | Fluctuation characteristics on slug liquid holdup and pressure,as well as the effects of gas and liquid superficial velocity on liquid holdup,were experimentally investigated by use of dual-parallel conducting probes.Besides,a comparison between prediction models of slug liquid holdup and test data was made.Using air and water,experiments were carried in the horizontal stainless steel pipe with 50 mm inner diameter.It was found that the curve of liquid holdup could response internal flow characteristics of slug flow more actually,so the fluctuation of slug liquid holdup could be used to determine liquid slug frequency.It also showed that slug liquid holdup decreased with the increase of gas superficial velocity,but increased with the increase of liquid superficial velocity. |
