Hello,
I want to design a room which has a fresh air inlet, outlet, and a recirculation zone so that certain amount of air can be recirculated back into the room.
I have my inlet as a velocity inlet, my outlet as pressure outlet, but I am really confused with the recirculating path boundary condition.
The geometry of the room is attached.
Can someone please help me with this problem. what boundary conditions should i use so that i can have a required amount (say 10% or 20%) of return air.

Thank you it works now

I have some more questions if you don't mind.

I have a model for indoor AC

The AC unit has two inlets (inlet1- for the recirculation of air indoor. inlet2- for getting fresh air from outside) and one outlet into the room

can I write a UDF that can help switch between AC inlets in fluent?

Dear all I am working on a problem which includes recirculation unfortunately with the above command I am unable to activate the recirculation. Could you please elaborate how to enable it?? Iam using ANSYS 15
