Influence of refrigeration oil on the heat transfer and pressure drop of supercritical CO2 during in-tube cooling.

Author(s) : ZINGERLI A., GROLL E. A.

Summary

For this purpose, test runs were conducted with pure carbon dioxide, and with 2 and 5% of refrigeration oil entrained in the flow. The experiments showed that a 5% oil concentration reduces the heat transfer coefficient on average by 25%, while a 2% oil concentration reduces the heat transfer coefficient on average by 15%.
