The combination of interdigitated flow fields (IDFF) with porous electrodes offers lower pressure drop and better performance than conventional flow‐through porous electrodes in redox flow batteries. Comprehensive three‐dimensional and simplified one‐dimensional + two‐dimensional models describing flow uniformity and pressure losses within flow through, parallel, and interdigitated flow fields were developed and used to demonstrate the benefits of IDFF. Analytical solutions for IDFF that compare favorably with computational fluid dynamics quantify the trade between pressure loss and velocity maldistribution both along the channels and within the electrode. © 2018 American Institute of Chemical Engineers AIChE J, 64: 3746–3755, 2018

模拟氧化还原液流电池中的流量分布和压降

与氧化还原液流电池中的传统流通式多孔电极相比，叉指式流场（IDFF）与多孔电极的结合提供了更低的压降和更好的性能。开发了全面的三维模型和简化的一维+二维模型，这些模型描述了流过，平行和叉指式流场内的流量均匀性和压力损失，并用于证明IDFF的优势。IDFF的分析解决方案可与计算流体动力学相提并论，从而量化了沿通道和电极内部的压力损失和速度分布不均之间的平衡。©2018美国化学工程师学会AIChE J，64：3746–3755，2018
