摘要：

Gas/liquid flow in laboratory-scale venturis has been studied experimentally. Water was introduced as a film upstream of the venturi operating with throat gas velocities of 53-73 ms(-1) and liquid to gas ratios in the range 0.75-21 m(-3). Two different throat lengths were examined. Measurements of film flow rates were made at the end of the throat and at the end of the diffuser. These were used to determine the split of liquid between film and drops. The results show that a significant fraction of the liquid remains as a film. The entrained fraction has been correlated in terms of a Weber number based on conditions at the throat entrance.
