Diffusion of Nano particles under electric field
 

Hello!

I am trying to simulate the diffusion of nanoparticles under an electric field.
There are both diffusion flux and electric flux.
My objective is to model this as a homogeneous mixture, without considering the electrostatic force on each nanoparticle.

Can someone please help me with this?
How can I combine the effect of the electric field with diffusion flux?

Please help!
Thank you..
