A correlation is developed for evaporation heat transfer inside a spirally grooved tube, and compared with the experimental data. First, heat transfer coefficients for pure refrigerants were correlated in a form such that two-phase flow pattern was taken into account. Next, a correlation for binary mixtures was derived from the correlation for pure refrigerants and the thermodynamic relations for mixtures. This is based on the model described in the previous report. The predicted heat transfer coefficients agreed with the experimental data with a mean deviation of 7.4% and 8.8% for pure refrigerants (R11,R114,R123) and binary mixtures (R11/R114,R123/R134a), respectively.
