- •
Computational analyses to judge the suitability of using supercritical fluid in NCL.
- •
Comparison of water, R134a & CO2 as loop fluid under identical operating conditions.
- •
Asymmetric temperature & velocity profiles due to buoyancy-induced local convection.
- •
Lowest mass inventory & largest heat transfer rate with CO2 under certain condition.
- •
Supercritical CO2 is better option when sink temperature is below pseudocritical.
