本文考虑了卤代丙烯异构体在管内冷凝和管内流动沸腾过程中的传热和压降性能潜力，分别使用惩罚因子和总温度惩罚的概念。特别地，考虑了五种异构体：R-1233 xf、R-1233 zd（E）、R-1234 yf、R-1234 ze（E）和R-1243 zf。此外，这五个纯流体，传热和压降性能潜力进行了研究的五个R-32/R-1234 yf混合物和27个混合物被认为是空调，加热和制冷研究所（AHRI）的低全球升温潜能值替代制冷剂评估计划的一部分。本文还给出了五种纯工质相对于R-134 a或R-123的热物性估算以及五种R-32/R-1234 yf混合工质相对于R-134 a的热物性估算。考虑的热物理性质是影响传热和压降性能潜力的性质，包括热力学性质温度、压力、密度、汽化潜热和比热，以及传输性质导热性和粘度。本文还对氟化丙烯同分异构体的冷凝、沸腾传热和压降的相关文献进行了综述。
This article considers the heat transfer and pressure drop performance potentials of halogenated propene isomers during in-tube condensation and in-tube flow boiling using the penalty factor and total temperature penalization concepts, respectively. In particular, five isomers are considered: R-1233xf, R-1233zd(E), R-1234yf, R-1234ze(E), and R-1243zf. In addition, to these five pure fluids, the heat transfer and pressure drop performance potentials are investigated for five R-32/R-1234yf blends and for twenty-seven blends being considered as part of the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) Low-GWP Alternative Refrigerants Evaluation Program. The article also presents thermophysical property estimations for the five pure fluids relative to R-134a or R-123, and the five R-32/R-1234yf blends relative to R-134a. The thermophysical properties considered are the ones that influence the heat transfer and pressure drop performance potentials, and include the thermodynamic properties temperature, pressure, density, latent heat of vaporization, and specific heat, and the transport properties thermal conductivity and viscosity. The article also presents a literature review of relevant articles for condensation and boiling heat transfer and pressure drop of fluorinated propene isomers.
