Flow electrodes modeling

I want to model a flow electrode where the fluid is a mixture of water and activated carbon with 1M Na2SO4. Can any one help me ? The two electrodes are separated with a nafion 114 membrane.

Thanks a lot for your reply. I need help to select the perfect physics. I have selected Nernst-Planck equation. First problem is in modeling the slurry mixture.

Then, the main problems arises for me to define the ion transport. In a aqueous solution mixed with carbon, how to define the role of carbon during ion transport.

Best regards

I deposited 45k with BKYHYO Ltd., a company that claimed to invest through platforms such as Binance and MetaTrader 5. The money was transferred directly from my bank account.When I later tried to withdraw my funds, the company suddenly demanded a “Tax Verification Fee” and gave me only two hours to make the payment. I deposited the requested amount, but instead of processing my withdrawal, they rejected the payment and demanded that I deposit even more money within four hours. Shortly afterward, my account was frozen, leaving me unable to access or withdraw my funds. Realizing that something was seriously wrong, I reported the matter to the authorities. I was eventually referred to a recovery company called Cyberberspy, which assisted me in recovering my money.If you have been affected by a similar situation and are considering a recovery service, I encourage you to look into Cyberberspy. In my experience, they were professional, persistent, and effective in helping me recover my funds. reach out to their suport. ( support@Cyberberspy.com)
