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.
