THE ONSET OF DROPLET ENTRAINMENT IN ANNULAR GAS-LIQUID FLOW
Experiments are reported in which droplet entrainment was measured for co-current flow of air-water mixtures in tubes. It was found possible to define a critical air velocity above which entraimnent of droplets occurred. Seven tube diameters were tested as weli as the effects of tube length, orientation, inlet design, sampling techniques, and liquid flow rate. The critical air velocity was found to be a weak function of liquid flow rate and to increase with a decrease in pipe size. A Weber Number criterion based on tube diameter, gas velocity, and density, is suggested as a possible transition criterion but further work is required in order to determine over what range of fluid properties and system variables this formulation may be valid.
