Abstract

Abstract: The radial distribution of the axial component of time-average liquid velocityand turbulent
intensity in a gas-liquid bubble column was investigatedexperimentally using LaserDoppler
Anemometer (LDA). The effects of operating parameters on liquidturbulent intensity
arestudied and an empirical relationship between turbulent intensity andviscosity was
established. Such a relationship can be used convenientlyin the calculation of
liquidvelocity profiles in bubble columns.

Key words: bubble column, liquid velocity field, turbulent intensity, turbulent viscosity
