Pressure gradient/ Skin friction in periodic flows
 
Hi fellows,

I'm trying to implement a wall model in an LES code to then apply body forces(pressure gradient) in a cyclic streamwise boundaries. My question is how are the pressure gradient and skin fiction should be balanced to have no flow acceleration.
