Heat transfer experiments in vertical tube were performed in Supercritical Water Thermal-hydraulic Mechanism Test (SCTM) Loop in Nuclear Power Institute of China. The test tube was 3.0 m long and the inner diameter of 6.0 mm. Experimental condition covered pressures of 23, 24 and 25MPa, mass flux of 600-1200 kg/m2•s, heat flux of 600-1100kW/m2, and bulk temperatures of 300-500℃. The experimental data were compared with several current correlations, respectively. It showed that these correlations could not predict heat transfer coefficient accurately in pseudo-critical area.
