Flow through Water Intake Bay
 

Hello All,

I am trying to model flow of water, in a multiple intake pump bay.

The Intake bay is rectangular shaped which has 4 pumps on one side for flow intake and 1 pump on another side.

The Mass flow rate of each pumps are known, however the suction pressure is an unknown parameter.

I have proceeded by giving

Opening Boundary condition with total pressure and direction at Inlet.
Zero gradient mass momentum option is given.
The bay takes in water from the sea/river which is located nearby and it is directly connected to it via a open channel.

The outlet boundary condition specified are individual mass flow rates at each pump station.

The a photo is attached showing the water intake bay and the boundary condition given at inlet.

Can someone tell me whether the given boundary conditions are correct.

As I get the velocity of flow at my inlet in the range of 900-1000 m/s.

Thanks in Advance
