Abstract

In this work, a comparative study of the flow boiling heat transfer coefficient of carbon dioxide (CO2) in evaporation is presented. The main objective of the this work is to analyze and evaluate 1886 experimental points of the CO2 heat transfer coefficient with the help of two evaporation correlations (Fang et al., 2013 and Fang et al., 2017); the correlation of Fang et al., 2017 gives the best results.
