it seems like you should have no problem warming air up 8 degrees when you have 75 degrees temperature difference between the two fluids... you just have to find the best configuration for your application.
can you slow down the air at all?
Although I don't have a clear picture of your situation in my head - I can suggest maybe you have a thickness of insulation where the increase in convection caused by the extra surface results in an increase in the heat transfer? see critical thickness of insulation in a heat transfer book if...
Thank you for all your suggestions cbiber, I will look into these.
Yes, it is air, and yes, I will be considering the extra pressure drop that they cause. I have been alloted a maximum pressure drop and believe we will be testing with software Fluent. But thanks for the reminder!
Any other...
Thanks, it sure does help
The closest I could find on the McGraw-Hill Website is the following:

Hello all,
I would like to ask your opinion on best books to analyse convection - forced and free - on plates vertical and horizontal, between two plates, and the effects of extended surfaces of various shapes on these plates.
Looking forward to hearing your suggestions
Regards,

I was asking myself the same question as "RE" above - and found the replies to be helpful. I was wondering if "25362" could tell me where he/she had gotten the equations to approximate h (h=1.42*(deltaT/L)^0.25) ?
Thank you
