This is a forced convection heat transfer problem and would appreciate any help!
Stack of steel billets is placed in a cooling chamber. All billets of the same row are touching each other and each row is spaced of 5 in. I want to calculate the convection coefficient and pressure drop across the bundle. Ultimately, I would like to calculate the heat transfer after 1 hour (billets temperature and heat loss)
Billets T = 1100 F
Air, v = 60 ft/s, T = 70 F
T = 1100 F ______________

OOOOOOOOOOO <-- Air, v = 60 ft/s, T = 70 F

____________________________
What I am thinking of is to calculate an average h because air velocity is very high between the billets but a stagnant zone will exist near the hollow of adjacent billets.
I don't know the governing equations and how to start this problem.
Thank you if you can help.
