- •
POE oil affects flow boiling pressure drop of CO2-oil mixture in micro-fin tube.
- •
Oil influences pressure drop in adiabatic conditions mainly at high vapor qualities.
- •
Established correlations do well describe the pressure drop in adiabatic conditions.
- •
At high heat flux, correlations fail in describing the pressure drop for woil,0 > 1.3%.
