中文摘要	对R134a、丙烷(C3H8)、异丁烷(iC4H10)三种纯工质以及它们相应的二元混合物和三元混合物做了池核沸腾传热实验研究。加热面为紫铜表面,压力范围在0.1~0.6MPa。在纯工质实验数据基础上,分析物性、压力对沸腾传热系数的影响。相对于纯工质,非共沸混合工质沸腾传热系数有所降低,并且在高热流下趋势更明显。最后拟合出纯工质和混合工质沸腾传热关联式。; Heat transfer coefficients in nucleate boiling on a smooth flat surface were measured for pure fluids of R-134a,propane,isobutene,and their binary and ternary mixtures at different pressures from 0.1 to 0.6 MPa. Series of experiments with different heat flux and mixture concentrations were conducted.Compared with the pure components,binary mixtures show lower heat transfer coefficients.This reduction was more obvious at the high heat flux.Several heat transfer correlations were obtained for pure refrigerants and multicomponent mixed-refrigerants.
