Abstract

An experimental study by using flush-mounted conductance probe sensors has been carried out in an air-water horizontal annular flow. The experiment was arranged in a 26-mm diameter pipe with superficial gas velocity of 10 to 40 m/s and superficial liquid velocity of 0.025 to 0.4 m/s. The probe detects the liquid film thickness at 7 circumferential positions from the bottom part to the top of the pipe and the liquid holdup is determined from the average of the circumferential liquid film thickness. A range of liquid holdup form 0.022 to 0.21 is resulted from the experiment. A decrease of liquid holdup is resulted with the increase superficial gas velocity and decrease of superficial liquid velocity. Conversely, the liquid holdup increases with the decrease of the gas velocity and the increase of liquid velocity. Examination of the experimental data by using 7 previous available correlations results in a reasonably good agreement.
