对四丁基溴化铵水合物浆体的流动特性进行了实验研究。以雷诺数、管径和固相率为实验参数，对实验结果进行了分析。对于层流，发现管道摩擦系数的比率随固体分数而增加，并且在低雷诺数的情况下增加的速率高。对于湍流，在低固体分数下，对于所有管直径，管摩擦系数的比率约为1。然后在特定的固相分数下略有下降，并在高固相分数下再次增加。利用实验结果进行了理论分析，发现水合物浆液的流动特性可以被视为假塑性流体，并使用表观雷诺数澄清。
The flow characteristics of a tetra-n-butyl ammonium bromide hydrate slurry were investigated experimentally. Reynolds number, tube diameter and solid fraction were varied as the experimental parameters. For laminar flow, it was found that the ratio of the coefficients of pipe friction increases with solid fraction, and the rate of increase is high in the case of a low Reynolds number. For turbulent flow, the ratio of the coefficients of pipe friction was approximately 1 for all tube diameters at low solids fraction. It then decreased slightly at a particular solid fraction and increased again at high solid fraction. Theoretical analysis was carried out using the experimental results, and it was found that the flow characteristics of the hydrate slurry can be treated as those of a pseudoplastic fluid and clarified using the apparent Reynolds number.
