    Abstract

    This paper reports an experimental study of the local and average heat transfer and the pressure drop of supercritical CO2 in multi-port channels. The results indicate that high rates of heat transfer coefficient are achieved in the near-critical region, and that the system pressure, the mass velocity and the temperature of CO2 all have important effects on the heat transfer characteristics. Based on large amounts of experimental data, a new empirical correlation was developed for forced convection of supercritical CO2 in horizontal mini/micro channels in cooling case.
