Electroosmotic in Fluent using Battery Model
 

Hi everyone, I need create an electroosmotic flow in Fluent, I want to inject a fluid on the channel and the wall the cylindrical channel has a electrical potencial, but I want either to put a electric current in the channel where the fluid is conductive, like this picture attached.

It's hard for me because I don't know how choice the properties in window of the Battery Model in Fluent and how create the zones and walls for anode, cathode, etc.

In Battery Model > Electric Field > Contact Surface > Which should be these zones? Does anyone have one model?

In Battery Model > Electric Field > External Connectors > How should be these connectors? Which the difference between their and the anode and cathode?

Which is anode-tap?

Sincerely,

Could you solve your problem? I am interested in the subject too.
