Spacer meshes in electrodialysis (ED) play a crucial role in influencing fluid and electric field distributions during mass transfer. This study employed finite element analysis using real‐world parameters to explore how spacer mesh geometry and material affect mass transport. Comparisons among different wire mesh configurations revealed increased fluid velocity near mesh wires and reduced electric field intensity nearby, enhancing overall transport efficiency. Increasing mesh count or wire diameter notably improves transport, with optimal results achieved when wire orientation aligns with fluid flow. Additionally, the study showed that spacer mesh conductivity significantly influences ED transport, particularly when it exceeds the conductivity of the solution. These findings advance the design and application of spacer meshes, offering valuable insights for future developments in ED technology.

通过有限元分析，通过间隔网格几何形状和材料电导率释放电渗析效率


电渗析 （ED） 中的间隔网格在传质过程中影响流体和电场分布方面起着至关重要的作用。本研究使用真实世界参数进行有限元分析，以探索间隔网格几何形状和材料如何影响质量传递。不同金属丝网配置之间的比较表明，金属丝附近的流体速度增加，附近的电场强度降低，从而提高了整体传输效率。增加网孔数或线径可显著改善运输，当线方向与流体流动一致时，可获得最佳结果。此外，研究表明，间隔网电导率会显著影响 ED 传输，尤其是当它超过溶液的电导率时。这些发现推进了间隔网格的设计和应用，为 ED 技术的未来发展提供了有价值的见解。
