Hi all,
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. Keng |
