摘　　要：以R113为工质,对不同当量直径管束通道内的流动传热特性进行了实验研究.在对单相强制对流实验数据与Sieder-Tate、Dittus-Boelter和Gnielinski公式的计算结果进行比较的基础上,得出了适合管束间狭窄通道的单相强制对流传热关联式;通过分析管束间狭窄通道中流动沸腾的传热特性,得到了可用于该通道的流动沸腾传热实验关联式,且计算值与实验值吻合较好.The heat transfer characteristic of tube bundle channel with different sizes was investigated experimentally by using Freon-113 as the working medium. The experimental data of single-phase forced convection heat transfer were compared with calculated values of the Sieder-Tate, Dittus-Boelter, and Gnielinski correlations respectively. Based on it, the correlation was developed for single-phase forced convection in this channel. The empirical correlation of flow boiling in tube bundle channel was also obtained, and the calculated value and the experimental value coincide well.
