摘　　要：提出环隙内流动沸腾传热计算的数学模型和计算方法。将传热系数K与流动沸腾传热系数hb的计算结果与实测数据加以比较。对环隙与空管两种结构的流动沸腾传热性能也进行了分析对比。A mathematical model and calculation method for heat transfer of flow boiling in annulus are proposed. Comparison of the predicted values of heat transfer coefficients K and boiling heat transfer coefficients h_b with those of experimental data are made, and the characteristics of heat transfer of flow boiling in annulal thermosyphon is compared with that in the closed one.
