The below post is related to an archived discussion

Hi, I am currently working on vanadium redox flow batteries. There is a Schloegl's equation in the membrane which relates the gradient of pressure and the electrolyte potential to the velocity of electrolyte in the membrane. I have a doubt regarding, how to input the the gradient of pressure and electrolyte potential.

Hello Rajat , I am working on the simulation of VRFB too, did you find the anwser?

Hi Boyuan Cheng

For the 2D model, you have to define two components of velovcity (in x and y directions) separately in the variable, then put those components in the membrane physics.

I hope it helps.
