Gas Radiation in Pipe Annulus
Gas Radiation in Pipe Annulus
(OP)
I'm trying to solve the heat transfer in a pipe annulus that transports combustion gas. My question is how to determine the view factors.
A few text books uses the electrical network analogy to solve radiation between 2 surfaces separated by an absorbing and transmitting medium (combuston gas in this case). Mostly a simple example of 2 infinite parallel plates are used to demonstrate the principle, where all the view factors are unity. However, I'm not sure what the typical view factors from the gas to the surfaces should be in the case of a pipe annulus. Any help will be appreciated.

Compositepro, the presence of just the H20 and CO2 molecules in a combustion gas (no flame and no soot) can have a significant contribution to the overall heat transfer at elevated temperatures. In our case we can unfortunately not neglect it.
