摘要(Abstract)：

由于μDMFC结构尺寸的减小致使CO2气体容易阻塞阳极沟道,影响沟道内的气液输运。含气率作为评估沟道气液输运特性的标准之一,但是目前的后处理过程难以直接获取蛇形沟道沿程截面含气率,因此针对FLUENT后处理进行二次开发。该二次开发程序通过GUI传递模型特征参数,基于MAYA的可视化交互环境进行参数化模型的实时显示,并以日志文件作为接口实现MAYA和FLUENT间的数据传递从而实现参数化建模,进而获取沟道沿程截面含气率数值。最后基于二次开发软件研究了一种新型流场板结构,并发现改变双层流场板沟道侧壁面润湿特性能有效改善沟道气液输运特性。此处理方法不仅为研究燃料电池沟道输运特性提供了有效的数据获取手段,也为研究气液两相流动现象提供了解决思路。
