I want to simulate in fluent a structure with 6 rows of steel that 22-degree water inter and pass through it then exit with 25-degree. There is a hot external airflow around this structure. Because of the periodic nature of rows, I want to simulate just one row and consider half of the distance between the rows for external airflow so after the period we will have full distance.
according to the fluent user guide, it's a no-pressure drop periodic flow and we must use the periodic boundary condition. So left and right walls of external airflow in the direction of x must be an interface and after making periodic boundary condition with these two interfaces, we have a periodic zone and side1 and side2 and I don't know which BC must specify to them.
I think I can use symmetry BC instead of the periodic boundary condition in this project🤔
You have to use TUI command for creating periodic boundary conditions. make-periodic option is there.
Hi Manuchehr,
you can use either symmetry or periodic boundary condition, but before decide on it should should make sure which suits your problem statement better. My advice would be to apply both and see how it reflects physically, whether it is the same with the complete geometry.
Let me know if you could understand what i meant, else i would explain.
Periodic boundary condition in Fluent has multiple options with and without pressure.
Hope it helps.
Thanks & Regards,
Rajesh.
