英文摘要：

Spinning band distillation（SBD） is a new separation technology,which can be applied to separate liquid compounds with the properties of close boiling point and thermo-sensitiveness. A model installation of SBD was designed and set for the measurement of fluid flow regimes. The high-speed camera was employed to record and study the liquid flow regimes on the wall of SBD column,and the photographs of liquid flow regimes were screened under different operational conditions. Moreover, a mathematical model of liquid flow regimes by Reynolds number was developed,and then a normal empirical formula for transition of different liquid flow regimes on the wall of SBD column was obtained,which will be a foundation for further studies on liquid flow and mass transfer of SBD.
