Default Boundary conditions for fully-developed turbulent channel flow

Hi Dear Foamers
I am trying to simulate a fully-developed turbulent channel (duct) flow under a constant known pressure drop using standard k-epsilon model.
I want to specify the fixed pressure values at the inlet and the outlet of the channel and other properties (U, k, epsilon an nut) to be periodic, but I found no appropriate BC.
If I use cyclic BC, it is impossible to specify pressure values and if I use pressureInletVelocity there is no chance to use cyclic BC for k, eps and nut.
I read some related posts but no solution found. Would someone help me please?
