Summary
The experiment was conducted to investigate the heat transfer of supercritical carbon dioxide in tubes. The effects of mass flux, pressure and inlet temperature on heat transfer characteristics and pressure drop were analyzed. The results show that the heat transfer coefficient is directly proportional to the mass flux, and it decreases with the increase of the pressure and does not vary with the inlet temperature. In addition, the pressure drop increases with the increase of the inlet temperature.
