DETERIORATION IN HEAT TRANSFER TO FLUIDS AT SUPERCRITICAL PRESSURE AND HIGH HEAT FLUXES. [PDF]

, 1968
At slightly supercritical pressure and in the neighborhood of the pseudo-critical temperature (defined as the temperature corresponding to the peak in specific heat at the operating pressure), the heat transfer coefficient between fluid and tube wall is strongly dependent on the heat flux.
