Dataset for Current distribution in a rectangular flow channel manufactured by 3D-printing

The characterization and improvement of a rectangular channel electrolyte flow compartment used in an iron-air flow battery was carried out by using an arrangement of copper electrodes to measure the current density distribution employing the limiting current technique. The present work addresses the hydrodynamics and mass transport distribution in the compartment and their improvement by an improved electrolyte compartment that results in a more uniform current distribution. The current distribution was evaluated as the ratio between the local and the averaged limiting current densities during the reduction of copper ions over a range of mean linear flow velocity across the electrode surface (2-30 cm s-1). The initial compartment, showed larger differences between the minimum and maximum currents than the electrolyte compartment that resulted as part of the design process and showed a higher pressure drop at a given mean linear flow velocity.

本研究采用极限电流技术，通过布置铜电极测量电流密度分布，对铁-空气液流电池所用矩形通道电解液流动室进行了表征与改进。本研究探讨了流动室内的流体动力学与传质分布特性，并通过优化电解液流动室设计以实现更均匀的电流分布，从而改善上述分布情况。在电极表面平均线性流速范围为2-30 cm/s的条件下，通过铜离子还原过程中局部与平均极限电流密度的比值来评估电流分布。初始流动室的最小与最大电流差值大于设计过程中优化后的电解液流动室，且在给定平均线性流速下表现出更高的压降。本数据支持以下出版物：Figueredo Rodriguez, Horacio、Mckerracher, Rachel、Ponce De Leon Albarran, Carlos与Walsh, Frank（2016）《3D打印矩形流动通道中的电流分布》，《AIChE Journal》，第1-35页（doi:10.1002/aic.15454）。
