As you can see, the film flow downwards on the wall,the model is 4.6mm wide and 500mm long,I use fluent to simulate, the liquid inlet sets as the constant velocity, the wall and the gas inlet set as no slip wall whose contact angle is 45,the outlet and the side contrary to the wall set as pressure outlet with its gauge pressure is 0Pa. When I simulate it ,it always give a "reverse flow in the pressure outlet(include the two boundary who set as pressure outlet boundary) ".Do you think it is reasonable?

my boundary is big enough,the wide is 4.6mm,the length is 500mm,I think there is no need to enlarge the boundary.And I think there is no reverse flow ,do you agree with me ?
