Inlet and Outlet Conditions for Concentration Profile Over Time

Please login with a confirmed email address before reporting spam

Hi, I have a little familiarity with COMSOL but, I suspect that what I'm trying to do is more advanced. I'm trying to model concentration depletion over time. My model is 2D with water flowing around a small rectangle that acts as an infinite sink for my species that is being diffused. Right now, the fluid flow is continuous and not recycled. I would like to model the fluid as being returned to the inlet to see how the concentration profile at the outlet changes over time.
