Abstract
The axial and tangential velocity components and local liquid holdup rates have been measured in vertical tubes with swirl bodies located in the inlet part of the tube. The tubes were of 70 mm I.D. and H/D = 10-23. The air-water flow was directed upward. Superficial gas velocity was wG = 14-35 m s-1 and specific liquid load QLE = 15-65 m3 m-2 h-1. In the experiments, the blade angle of the swirl body and the liquid inlet have been altered. The resulting centrifugal moments were correlated with friction factors.
