Pressure gradient for channel flow??
 
Hi

I am running a plane channel flow using periodic boundary. I have specified pressure drop between inlet and outlet. Do I need to set pressure gradient as well under sub-domain??

Thank you for your help.

Re: Pressure gradient for channel flow??
 
No. The pressure drop comes from the pressure loss of the flow through your modelled domain.
