Can any one please tell me that how to get filly developed flow of air through rectangular pipe in Open Foam , i m using simple foam but not getting fully developed flow,only inlet showing the vectorial view of air not the full mesh including outlet too???M using pitzDaily for solving this problem.

Did you save a Iteration step ?

1. where is your inlet
2. are the vector orientations correct or do you want to have a flow from left to right?

3. with your smart description and Information ist not possible to give a hint.

Hello Tobi,

I would like to implement fully developed flow through a T-junction having one inlet with two outlets(also for two inlets with one outlet). It is having rectangular cross-section.

I am using Caelus 6.04 which is similar to OpenFoam.

Can you help me in implementing the fully developed velocity boundary condition at the inlet(s).

Thanks & Regards,
vidyadhar
