摘 要:This paper is ***,the effect of non-linear thermophysical property variation was presented using supercritical carbon dioxide(SCO_(2))around the thermodynamic pivotal *** second part exhibits an experimental examination of the heat transfer(HT)behaviour of SCO_(2) 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 ***_(2) was cooled in a 2 mm diameter serpentine tube made of copper *** experimental results showed that HT degradation could happen under the circumstances of a change in HF and MF and have significant effects on fluid inflow and HT ***,buoyancy plays an essential and influential role in the HT *** increasing the pressure value,the HT parameters decrease when the pressure reaches 8 MPa,and the flotation value is more significant,which means a decrease in the HT ***,under the system circumstances,the HT value decreases with the increase in heat flux and pressure and increases with the increment in MF.
