Experimental investigation for flow boiling of pure CO2 and CO2-oil mixture inside horizontal copper tubes.

Author(s) : KOYAMA S., ITO D., LEE S. M., et al.

Summary

In this study, experiments on the flow boiling of pure CO2 and CO2-PAG oil mixtures were carried out using smooth and micro-fin copper tubes as the inner tube. By comparing the experimental results obtained using almost pure CO2 and CO2-oil mixtures, it was confirmed that the oil concentration effects on heat transfer coefficient and pressure drop in micro-fin tubes have different characteristics from those of smooth tubes.
