Boundary Condition for Return Air
I am a beginner in CFD, anyway, I am having problem as in the mentioned subject.
I am trying to simulate an indoor air flow condition for a lecture room.
From the plan I have, I obtained all locations for both supply and return ducts.
The capacity for both of them are listed in cubic feet per minute (cfm), I already converted them to meter cube per sec.
For the Supply ducts, I can obtained the capacity easily, Area X Inlet Speed = meter cube per sec.
But I am having problem with the Return ducts, most of the boundary conditions require the temperature, which I do not have.
So, to recap my question, Which type of Boundary Conditions should I specified for Return Air ducts? Information I have, capacity and size of each return air ducts.
Thanks for ur time.
