Résumé

Tube-side heat transfer coefficients for single-phase flow, evaporation, and condensation, are presented for propane (R290), isobutane (R600a), and a 50/50 mixture (by weight). Heat transfer coefficients have been presented for smooth tubes based on the standard correlations available in the literature for pure refrigerants. The correlations for evaporation and condensation have previously been verified for R12 and other refrigerants. The mass flux of the refrigerants is varied over a wide range. Evaporation temperatures of -7 and 4 deg C and condensation temperatures of 38 and 49 deg C have been used for this investigation.
