Experimental investigation of near-critical CO2 heat transfer performance in a closed natural circulation loop

Examining the potential of sigma-thermic heat transfer fluid and its nanofluid in a natural circulation loop through CFD studies

“…Most of the results obtained through experimental data are compared with Vijayan's correlations to validate their accuracy and are used to develop a large-scale loop. Y Li et al [17] investigated the natural circulation loop experimentally from the pressure region of subcritical to supercritical on carbon dioxide as loop fluid. According to experimental data, the heating component of the loop demonstrated degradation in heat transfer at supercritical pressures despite the loop having outstanding heat transfer capabilities at subcritical pressure.…”
