摘要：

The liquid-phase turbulent structure of an air-water, bubbly upflow in a circular pipe has been investigated experimentally. Liquid-phase local velocities and turbulent stresses were simultaneously measured, using both one- and two-dimensional hot-film anemometer probes. A highly-accurate digital process method, based on threshold combinations of level and slope, was developed to identify the phases. Systematic measurements were conducted under 48 flow conditions covering a range of local void fraction from 0 to 50%. The important experimental results and parametric trends are summarized and discussed. Finally, the present data are compared with some other data sources and existing models.
