Temperature profile along a Honeycomb Ceramic Cylinder

[marc400317]

Hello everyone, I have to do some calculations on an existing honeycomb cylinder-shape made of ceramic material. Dia= 500mm and Length: 600mm. The cylinder will be connected to a gas turbine combustor outlet by a S.S pipe with air temperature reaching 1000deg and mass flow 4.1 kg/s. I need help please with the following 2 points:
1. I need to calculate the temperature profile along the Honeycomb Ceramic Cylinder without being insulated.
2. I am trying to deduct a formulas that relates the size of each honeycomb opening ( small rectangular shape 1mmx1mm)to the temperature profile.
I am fairly new in the heat transfer area, any help at this stage would be very much appreciated.
Thanks

Temperature profile which way, radially or axially?

1000ºC, 1000K, 1000ºF??

air temp?
Ceramic thickness, thermal conductivity, emissivity?

Thanks for your reply, I guess my question should have been asking for a general rule to solve this problem, or formulas. I already requested this book from our library, is there any chapters I should be focusing on?
Thanks

I hope that you realize that there's not going to be a simple solution to your problem. Your best bet is probably to run FEA on the problem.
