| Abstract: | Frictional pressure drop of air-water two-phase flow was studied in a vertical helicoidal coiled tube.Based on previous studies,a new calculation formula was obtained from our present data.It can be applied in the situation of low pressure（lower than 1 MPa） and low mass flow [lower than 150 kg/（m2·s）].[Ch,5 fig.8 ref.] |
