Hello, I am currently working on impingement heat transfer and flow characteristics using Star-CCM+.

What would you recommend as boundary conditions for the top and side sections of the domain? A zero gradient boundary would be a good choice for the side and an entrainment condition for the top of the domain maybe? But how would I implement the same?

PS: I have attached an image of the setup.

Thanks in advance.
