| Abstract: |
| This paper gives a review of the heat transfer and pressure drop characteristics of supercritical carbon dioxide in-tube flow.Some published correlations for heat transfer coefficient and pressure drop during in-tube cooling are collected.The accuracy of the correlations are discussed through comparing the calculation results with the experimental data.The shortages of current researches are pointed out. |
| Key words: Pgrology,correlation supercritical,carbon dioxide,heat transfer,pressure drop |
