Average wall heat transfer coefficient: Does this include radiation as well?

yaquadir · April 9, 2014, 09:07

Hi. A quick question to all. I am able to get the average wall heat transfer coefficient from CFX post (function calculator). What I want to know is whether this coefficient is purely convective or is radiation also taken into account.
Thanks in advance!

Yes, radiation is taken into account.

This is covered in the CFX documentation. If you searched it for 'wall heat transfer coefficient' you'd have your answer.
