Abstract
This paper presents an overview of the flow boiling heat transfer characteristics and the special thermo-physical properties of CO 2 at low temperatures (down to −30 °C). Subsequently, the boiling heat transfer of CO 2 at low temperatures is experimentally investigated in a horizontal tube with inner diameter of 4.57 mm. Due to the large surface tension, the boiling heat transfer coefficient of CO 2 is found to be much lower at low temperatures but it increases with vapour quality (until dryout), which is contrary to the trend at high temperatures around 0 °C. None of the empirical correlations from open literature were able to predict the boiling heat transfer coefficient for CO 2 in good agreement with the experimental data, suggesting the need for further research in this area.
