Refrigerant vaporization inside enhanced tubes: a heat transfer model.

Author(s) : CAVALLINI A., DEL COL D., DORETTI L., LONGO G. A., ROSSETTO L.

Summary

The proposed model takes into account the nucleate boiling and the forced convection contributions and the effect of the heat transfer surface geometry. The model has also been extended to zeotropic mixtures taking into account Thome (1994) correction for pool boiling and Bell and Ghaly (1973) correction for interphase mass and heat transfer. Results are compared with available data for R407C and R32/R134a mixtures. Agreement between experimental and calculated values is good.
