How to model a chemical reaction with diffusion in COMSOL?

Please login with a confirmed email address before reporting spam

Hi,

I really hope someone can help me. I'm trying to simulate this problem for a little bonus in my master thesis, which is due in 3 weeks.

I simplified the geometry for the sake of simplicity, but the rest is pretty much the same. I have a rectangle filled with water. One face of this rectangle is at a constant concentration of a chemical species. The opposite face is has a constant production rate of another chemical species. These chemical species diffuse into the water.

These to species then react with eachother to form another species. I would like to simulate the concentrations of all of these species in time. I drew something to hopefully make my problem more clear:

I have tried to use the chemical engineering toolbox to do this but the assumptions that the different reactors make are not suited for my problem. Should I use the chemistry toolbox? I cannot seem to model my reactions in this though. Can someone please explain to me how to do this? I would be forever grateful.

Thanks,
Evan
