对冰带结构进行了实验研究，冰带结构的稳态冰剖面沿管道长度沿着呈周期性收缩和膨胀的变化。提出了冰带间距、收缩区换热系数和管内摩擦系数的关联式。通过引入基于总压的修正雷诺数，得到了管道冻结的条件。
The ice-band structure of which steady-state ice profile had a variation of flow passage with a cyclic pattern of contractions and expansions along the length of a pipe was investigated experimentally. Correlation equations were proposed for the spacing of the ice-bands, the heat transfer coefficient in the contraction region and the friction factor in the pipe. The conditions for pipe freeze-off were obtained by introducing a modified Reynolds number based on a total pressure.
