Default Inlet-outlet BCs
Posts: n/a
I am modeling(and coding) a 2-D flow in a fairly long plane channel domain with inlet and outlet boundaries . The source (electrical forces) of the flow lies fairly away from these boundaries.

Can you help me with your comments/suggestions/corrections/improvements/remedies on the following BCs ? I would be happy to get pointers to relevant papers/books etc.

At inlet and outlet :

1. Pressure = given 2. Normal derivative of the tangential velocity=0

(On walls:u=v=0+symmetry BC)
