Summary

This paper presents a comprehensive review on the flow boiling heat transfer of CO2-lubricant mixtures. Some of the immiscible lubricants in CO2 include alkyl naphthalene/alkylbenzene and polyalphaolefin, while polyalkylene glycol is partially miscible, and polyol ester is completely miscible. The effect of oil concentration, vapour quality, heat and mass fluxes and saturation temperature is addressed. One database has been created by collecting the experimental data from the open literature on the flow boiling heat transfer of CO2-lubricant mixtures, along with empirical correlations. A simple simulation model has been developed in EES software package to compare the empirical correlations with the CO2-lubricant mixtures experimental database. Most empirical correlations fail to predict the flow boiling heat transfer coefficient in good agreement with the experimental data. Hence, further research is needed to develop appropriate correlations for the flow boiling heat transfer of CO2-lubricant mixtures. [Reprinted with permission from Elsevier. Copyright, 2008].
