β¦ Synopsis
In this paper, an experimental study on the heat transfer characteristics of two phase flow boiling of ternary non-azeotropic refrigerant mixtures, as well as I-IFC-134a, inside water/refrigerant horizontal enhanced surface tubing, is presented. Correlations were proposed to predict the boiling heat transfer coefficients and pressure drop, as a function of the flow key parameters.
