a question on modeling natural ventilation
 

Does anybody knows, in modeling wind-driven natural ventilation, if set fixed flow (such as using fixed-flow in Flovent) around building, i.e. set fixed flow speed gradient along the height of the domain, and use turbulence model, such as k-e model, is the result reliable?

And, if this is ok, how to deal with the backgroud settingin Flovent, which also includes something about speeds and directions?

Thank in advance!

Ask again, thanks
