tracer profile in recirculation-tank

bioman6666 · March 19, 2011, 01:27

hello everyone:
I want to simulate a tracer distributed in a recirculation tank. This tank has three port. Port 1 is located on the top wall to inject tracer (dye); port 2 is located on upper side wall and connected with port 3 on the lower side wall by a tubing. The water is recirculating from port 3 to port 2 by a virtual pump in the tubing. How do I set the domain and boundary conditions on port 2 and port 3 to generate a recirculation?
Thank you !!

Either use an inlet/outlet pair or a momentum source. You might also be able to do it using a periodic interface boundary.
