Abstract This paper is twofold. First, the effect of non-linear thermophysical property variation was presented using
supercritical carbon dioxide (SCO2) around the thermodynamic pivotal point. The second part exhibits an
experimental examination of the heat transfer (HT) behaviour of SCO2 in a helical tube with a hydraulic diameter
of 2 mm at different mass fluxes (MF), heat fluxes (HF), and pressures (P). The experiments were carried out
based on various pressures, mass fluxes, and heat fluxes for both scenarios. CO2 was cooled in a 2 mm diameter
serpentine tube made of copper material. The experimental results showed that HT degradation could… More >
