An experimental study of liquid entrainment from swelled two-phase mixture surface in a vessel has been performed. To investigate the effects of air flow rate and initial water level on the liquid entrainment a series of experiments have been performed using air and water as working fluid. A total of 64 experimental liquid entrainment rate data have been obtained for various combinations of the test parameters (i.e., six different initial water levels and varying air flow rates from 0 lpm to 1200 lpm ) using two test vessels of the same height but with different inner areas (D = 0.15m and 0.30m,respectively) for vertical bubbly and churn-turbulent flow conditions. An empirical correlation for the liquid entrainment rate, E has been developed in terms of the superficial velocity of air, the initial water level, the density of gas, the surface tension, and the gravity. This correlation shows a good agreement with the present experimental data within ± 30%.
