AB - Experimental results of adiabatic two-phase pressure drop in small diameter  tubes are presented in this work. Air-water mixture is used as the working  substance. Four test sections made of transparent acrylic tubes of different  internal diameters ranging from 3.0 mm to 8.0 mm are used with different test  section lengths from 150 mm to 400 mm. The investigation is carried out  within the range of mass flux of water 16.58 -3050 kg/m2s, mass flux of air  8.25-204.10 kg/m2s and total mass flux 99.93-3184.69 kg/m2s. Some of the  existing correlations for macro and mini-channels are compared with the  experimental data. Based on the experimental data; a new correlation has been  developed to predict two-phase pressure drop in horizontal channels.
