Supercritical-water heat transfer in a vertical bare tube

Numerical investigation of heat transfer characteristics and flow resistance of kerosene RP-3 under supercritical pressure

“…Mokry et al [8] confirmed that there were three heat-transfer regimes for forced-convective heat transfer to water flowing inside tubes at supercritical pressures: namely, the normal heat-transfer regime, the deteriorated heat-transfer regime and the improved heat-transfer regime. The appearance and magnitude of the deteriorated and improved heat-transfer regimes were affected by pressure, bulk fluid temperature, mass flux and heat flux.…”

“…The existing investigations into supercritical fluids are mainly focused on water and carbon dioxide [8][9][10][11][12][13][14][15][16][17][18][19][20][21]. Mokry et al [8] confirmed that there were three heat-transfer regimes for forced-convective heat transfer to water flowing inside tubes at supercritical pressures: namely, the normal heat-transfer regime, the deteriorated heat-transfer regime and the improved heat-transfer regime.…”

Comparison between heat transfer to supercritical water in a smooth tube and in an internally ribbed tube

“…One of the most important features resulting from property variations is the abnormal heat transfer, i.e. enhanced heat transfer and deteriorated heat transfer (definitions of these two terms are specified in [2]). When the former occurs, heat transfer coefficient can be as high as 70 kW/(m 2 K) and heated tubes can be cooled with high efficiency [3][4][5][6], which is of great interest in supercritical water boilers and reactors.…”

Review of the Wall Temperature Prediction Capability of Available Correlations for Heat Transfer at Supercritical Conditions of Water

“…Many applications of supercritical fluids like power engineering, aerospace engineering, and refrigeration engineering have been mentioned in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Water at supercritical conditions is largely used in fossil fuel fired boilers [5].…”
