title = "Rans simulation of a radial compressor with supercritical CO2 fluid for external loss model development",
abstract = "From the observation of previous experimental results, it wasrecognized that the amount of external losses at the external flowpaths can be substantial. Understanding the external lossmechanisms, and reducing the external losses are crucial to thedesign of a high performance S-CO2 compressor. Therefore, thisstudy first focused on verifying the existing external loss modelsby estimating the internal loss accurately through a high fidelityCFD calculation and then substituting from the total losses. Byanalyzing the CFD result and energy balance data obtained fromthe experiment, the authors are suggesting the best combinationof the external loss models for the S-CO2 compressor. This isfollowed by the investigation of the condensation effect in theimpeller by utilizing a two-phase VOF model with metastableproperties. As a result, it is re-confirmed that there is a negligibleamount of condensation effect.",
