研究了四丁基溴化铵（TBAB）水溶液和笼形水合物浆液（CHS）在套管式换热器（DHE）中的流动和传热特性。对TBAB水溶液在过冷状态和正常状态下进行了测试，以了解过冷状态对TBAB水溶液流动和传热的影响。测量了5-25wt% TBAB CHS在无热交换条件下流经DHE的压降，得到了相应的流动摩擦系数，同时也得到了TBAB CHS流动熔化和生成的压降。给出了10-25wt%四丁基溴化铵CHS在换热器内流动熔化的单侧传热系数，并考虑潜热对传热的影响，建立了局部传热关联式。此外，在TBAB CHS生成过程中的传热被发现是恶化的传热表面上的晶体的粘附，并通过熔化操作的传热改善。
This study presents the flow and heat transfer characteristics of tetra-n-butyl ammonium bromide (TBAB) aqueous solution and clathrate hydrate slurry (CHS) in a double-tube heat exchanger (DHE). Both the TBAB aqueous solutions at the supercooling state and normal state were tested to understand the influence of supercooling state on the flow and heat transfer of TBAB aqueous solution. Pressure drops of 5–25wt% TBAB CHS flowing through DHE without heat exchange were measured and the corresponding flow friction factor was obtained, while the pressure drops of the flow melting and generating of TBAB CHS were also obtained. Single side heat transfer coefficients of the flow melting of 10–25wt% TBAB CHS in the heat exchanger were presented, and the local heat transfer correlation was developed with the consideration of the effect of latent heat on the heat transfer. Moreover, the heat transfer during TBAB CHS generation process was found to be deteriorated by the adherence of crystals on the heat transfer surface, and the heat transfer improvement by the melting operation was shown.
