Abstract

Flow behaviour of a capillary tube in the transcritical CO2 cycle is predicted based on homogeneous and separated two-phase flow models. Five different empirical correlations of void fraction available in open literature are used to predict the flow behaviour by separated two-phase model. Fauske [1] void fraction correlation matches reasonable well with homogeneous flow model with the discrepancy in capillary tube prediction as around 2%. It is observed that the homogeneous flow model is sufficient enough and recommended to predict the capillary tube flow in a transcritical CO2 system used for capillary tube modelling due to its simplicity and relatively lesser computations.
