Innovative approach to correlate heat-transfer data to supecritical carbon dioxide flowing upward in a bare tube

Existing literature on problems of heat transfer to fluids at supercritical pressures distinguishes three heat-transfer regimes: 1) Deteriorated, 2) normal, and 3) enhanced. Conventional approach to correlate forced-convective heat transfer to supercritical fluids is applied to the normal and enhanced heat-transfer regimes. Although, there were recent attempts to correlate data for the deteriorated heat-transfer regime at mixed convection, …
