Hey,
I don’t know your duct geometry. If you have to set a special pertubated flow at the inflow, you can’t deal with periodic boundaries. You can test the channel flow with inlet and outlet conditions, but I think it will be a hard task and you will be not able to compare any achieved statistics in the channel flow.
