Review on Heat Transfer of Subcritical Carbon Dioxide |

() |
Abstract: |
This paper gives a review of the heat transfer characteristics of subcritical carbon dioxide in-tube flow. Some published correlations for heat transfer coefficient during in-tube flow are collected. The accuracy of the correlations is discussed through comparing the calculation results with the experimental data. The applicable correlations in different conditions are recommended. |
