本文在美国-美国实验室条件下，对Flibe模拟流体（氢氧化钾水溶液）流动的磁流体效应进行了研究。日本JUPITER-II合作计划使用加州大学洛杉矶分校的“FLIHY”管流设施。在恒定热流条件下，利用热电偶探头测量了低雷诺数湍流条件下导热壁管内的平均温度和脉动温度。结果表明，即使在管道横截面上存在很小的温差的情况下，温度分布的特征也是湍流产生、磁场对湍流的抑制和热分层之间的相互作用。
Abstract An investigation of MHD effects on Flibe simulant fluid (aqueous potassium hydroxide solution) flows has been conducted under the U.S.-Japan JUPITER-II collaboration program using “FLIHY” pipe flow facility at UCLA. Mean and fluctuating temperature profiles in a conducting wall pipe were measured for low Reynolds number turbulent flows using a thermocouples probe at constant heat flux condition. It is suggested that the temperature profiles are characterized by interaction between turbulence production, turbulence suppression due to magnetic field and thermal stratification occurred even under the situation where quite small temperature difference exists in the pipe cross-section.
