中文摘要	Flow boiling heat transfer characteristics of 1,1,1,2-tetrafluoroethane (R134a) were experimentally investigated in a horizontal stainless steel mini tube. The inner diameter of the test tube is 1.3 mm, and the tube wall thickness is 0.1 mm. Local heat transfer coefficients are obtained over a range of vapor qualities up to 0.8, mass fluxes from (310 to 860) kg.m(-2).s(-1), heat fluxes from (21 to 50) kW.m(-2), and saturation pressures from (0.65 to 0.75) MPa. The dependences of heat transfer coefficients on mass flux, heat flux, saturation pressure, and vapor quality are demonstrated. On the basis of ail available model in recent literature, potential heat transfer mechanisms are also analyzed.
