A physically improved semi-empirical correlation for the forced convection heat transfer of supercritical CO2 within the PCHE was developed by implementing probability density function-based property revised technique.

Experimental and numerical investigations on forced convection heat transfer of supercritical CO2 within a semi-circular printed circuit heat exchanger have been performed.

The heat transfer effectiveness of supercritical CO2 in the cooling mode is better than that in the heating mode due to the reverse distribution of the thermo-physical properties in the radial direction.

The physically improved PDF-based correlation works better than the conventional DB and Jackson correlations by capturing more than 90% of the data within an accuracy of 25%.
