Abstract: An experimental study of two-phase pressure drop in small diameter tubes is described in this paper. Stainless steel tubes of internal diameter and length of 4.26 mm, 500 mm and 2.01 mm, 211 mm were used. The working fluid was R134a and the range covered was: mass flux 100 – 500 kg/m2s; system pressure 8-14 bar and exit quality up to 0.9. The heat flux applied to the tubes ranged from 13 – 150 kW/m2. The effect of diameter on pressure drop is discussed in this paper and a detailed presentation of the results of the comparison with existing pressure drop correlations, some particularly developed for small tubes, is given.
