## Abstract The effect of tube diameter on twoβphase flow patterns was investigated in circular tubes with inner diameters of 0.6, 1.2, 1.7, 2.6, and 3.4βmm using air and water. The gas and liquid superficial velocity ranges were 0.01β50 and 0.01β3βm/s, respectively. The gas and liquid flow rates w
Measurements of the liquid film profile and pressure drop were made in tubes with grooves of varying angle (0Β°, 9Β°a nd 18Β°) as well as tubes with varying numbers of grooves at a common angle (18Β°). These data indicate that the grooves act to redistribute the liquid film on the inner wall perimeter a
