Pbkp_rediction of condensation of refrigerant mixtures under magnetic field inside enhanced surface tubing

Abstract:

Two phase flow heat transfer characteristics observed under magnetic field during condensation of refrigerant mixtures R-404A, R407C and R507 as well as R-410A were observed, analyzed and presented in this paper. Experiments showed that magnetic field tends to enhance the condensation characteristics at lower Reynolds numbers. The data clearly indicated that values of the condensation heat transfer coefficient of refrigerant mixtures under investigation were significantly influenced by the Magnetohyrdodynamic (MHD) effects depending upon the type of refrigerant mixture. The proposed correlation appears to pbkp_redict the heat transfer coefficient with an average deviation of ± 10. © 2006 Elsevier Ltd. All rights reserved.
