@inproceedings{Yamashita2003HeatTS, title={Heat Transfer Study Under Supercritical Pressure Conditions}, author={Tohru Yamashita and Suguru Yoshida and Hideo Mori and Shinichi Morooka and Hideo Komita and Kouji Nishida}, year={2003} }

Experiments were performed on heat transfer and pressure drop of a supercritical pressure fluid flowing upward in a uniformly heated vertical tube of a small diameter, using HCFC22 as a test fluid. Following results were obtained. (1) Characteristics of the heat transfer are similar to those for the tubes of large diameter. (2) The effect of tube diameter on the heat transfer was seen for a ‘normal heat transfer, but not for a ‘deteriorated’ heat transfer. (3) The limit heat flux for the…
