摘要

电渗析（ED）中的间隔网在影响传质过程中的流体和电场分布方面起着至关重要的作用。本研究采用实际参数进行有限元分析，以探讨间隔网的几何形状和材料如何影响传质。不同金属丝网配置之间的比较显示，网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。增加网目数或金属丝直径可显著提高传输效率，当金属丝方向与流体流向一致时，传输效果最佳。此外，研究还表明，间隔网的电导率对 ED 传输有显著影响，尤其是当其电导率超过溶液电导率时。这些发现推动了间隔网的设计和应用，为未来 ED 技术的发展提供了宝贵的见解。

Unlocking electrodialysis efficiency with spacer mesh geometry and material conductivity via finite element analysis

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.
