3D schematic model showed in pic

help me to Descripted Bonudary Conditions and meshing model.

I thank you ahead for your help.

u can break B.C 2 and B.C 4 in to two boundaries while define them in Gambit. So u can handle better while air and water are separated. Then for water u can choose mass flow inlet and out flow, and for air u can choose both of them pressure outlet in the left and right side.
I'm here for more comments of others.

This pic showed my model whitout mesh.
but

The model meshed showed in pic.
Mesh around an obstacle with a high density that quad/tri used for mesh surface. and other surface used quad(map).
Is it OK?
what is mesh model better?
