Summary

Two-phase heat transfer and pressure drop of LNG (liquefied natural gas) have been measured in a horizontal smooth tube with an inner diameter of 8 mm. The experiments were conducted at inlet pressures from 0.3 to 0.7 MPa with a heat flux of 8–36 kW m-2, and mass flux of 49.2–201.8 kg m-2 s-1. The effect of vapor quality, inlet pressure, heat flux and mass flux on the heat transfer characteristic are discussed. The comparisons of the experimental data with the predicted value by existing correlations are analyzed. The Zou et al. (2010) correlation shows the best accuracy with a 24.1% RMS deviation among them. Moreover four frictional pressure drop methods are also chosen to compare with the experimental database.
