mass transfer

Hello everyone,

I would like to obtain the equation for mass transfer of contaminant in a river. Here the fluid flow is laminar and I don't have reaction. I solved it and obtained this equation, but I think this equation is wrong because when I solved it numerically and compare the results with comsol simulation, I got wrong answers. Would you please help?

Thanks a lot

I solved it again when it is steady state and laminar flow. Are my boundary conditions correct? What should I do for the next step?

Hello,

You can use the comsol help in order to see which equation comsol use for mass transfer and what are the assumptions.
