@Nidum:
Yes, it is forced convection, I never said otherwise. I'm calculating the air velocity "from scratch" so in order to know how the ducting arrangement and the cooling fan type/size I must calculate before the air velocity.
@Chestermiller:
Calculate U experimentally? Can you give me...
Hello, this is my first post. This question is related to my final thesis.
I'm calculating the heat exchange area of a radiator through heat exchange equations:
Q = U*A*LMTD
I have as data Q, and LMTD (this one through trivial calculations)
In order to calculate U, I need the coefficients...
