This dissertation deals with the heat transfer in heated tubular flows at supercritical pressures. Experimental data on supercritical heat transfer and mathematical models for its description were acquired from the literature. Using the high pressure evaporation rig HIPER, further data were generated. Using the new data and the data acquired from literature, the models for describing the heat transfer at supercritical pressures were evaluated. Also, a new model for the prediction of the heat flux density beyond which the heat transfer is deteriorated, was developed.
