Periodic boundary condition – Fully Developed Flow

[Miladfarahi957]

I have heat transfer problem.

My geometry is periodic in the y direction (Translational) and the top curved face is a wall. while the other sides have symmetry boundary conditions.

My question is that does defining a periodic boundary condition ( mass flow rate) means that the flow is considered fully developed?

if not how am I supposed to define it as there are no option to choose the mass flow rate as udf or expression?

Additional Information & Question:

I did the simulation with the following boundary conditions:

The following are the results I got after the simulation:

Periodic Condition-After- Simulation


Bulk-Temp.

 

Temp countor on wall:



My BC is static wall temp.! why does BC looks like this. why is it changing. and max temp in my simulation is 50. why do I have 52.6 here?

I don't understand the problem.

Please help.

I can tell that if u use periodic BC then it means fully developed flow-i also use the periodic BC along a pipe and i get fully developed flow, but i have no temperature equations.

Thank you. that helps.
