“…For example, a well-known correlation developed by Jung et al [6] using experimental results of the fluid mixtures R22/R114 and R12/R152a failed to predict the test data from other independent research groups, i.e. deviations of 54 %, 116 % and 62 % were reported by Rabah and Kabelac [7] for propane/R134a, by Chiou et al [8] for R22/R124 and by Grauso et al [9] for CO2/Propane, respectively. Currently, the poor predictive performance of existing heat transfer correlations hinders the development of thermodynamic cycles using zeotropic mixtures.…”

“…Especially, lower pressure drop and higher HTC were obtained for the mixture of R134a/R245fa with 0.82/0.18 than that of its pure fluid. Grauso et al [90] carried out an experimental study on the flow boiling of CO2 and propane mixtures (with 83.2/16.8 % and 70.0/30.0 % in mass concentrations) in a smooth horizontal tube with a 6 mm in internal diameter. The HTCs obtained in their study were remarkably degraded compared with the ideal heat transfer coefficient.…”

This paper reviews the state-of-the-art knowledge of boiling heat transfer in binary mixtures, special emphasis is placed on refrigeration industry. The advantage of using refrigerant mixtures over pure refrigerants include the enhancement of coefficient of performance (COP), better match with the desired thermal load and safer, more environmental-friendly refrigerants. In other words, the concept of using mixtures enables more flexibility for the selection of suitable working fluids in particular applications. The purpose of this review article aims to summarize the important published articles on boiling heat transfer in binary mixtures and innovative technologies, as well as to identify limitations to existing studies and directions for future research of this promising thermal management technique. The present article reviews straightforward on both pool boiling and flow boiling in a systematic and comprehensive way. This article maily focus on the review of the effects of mass diffusion, heating surface characteristics, heats from dilution and dissolution on pool boiling heat transfer of binary mixtures, as well as the effects of flow orientation, flow regime and flow instability on flow boiling heat transfer of binary mixtures. Many papers reviewed herein relate to the heat transfer correlations during boiling of binary mixtures. The review reveals that numerical simulations of boiling in binary mixtures, the benefits of surface modification on boiling of binary mixtures and the flow boiling of highly viscous pseudo-plastic mixtures have been scarcely investigated and require further investigation.

“…There have been a few comparisons of this method with data, some showing good agreement and some showing poor agreement. For example Grauso et al [5] found this method unsatisfactory while Zurcher et al [6] showed that this method worked well for their R-407C data. Barbosa and Hewitt [7] pointed out that there is also a mass transfer resistance at the liquid-vapor interface in flow without nucleation due to the difference in composition between the liquid and the bulk vapor.…”
