Good days,
I am trying to simulate a natural gas combusted air heater.
unfortunately, there is not a combustion model for sim cfd.
I am trying to model it as a 0.99 resistance metarial with a heat generation and created a flue gas metarial with its thermodynamic properties then with a volume flow rate moved it through to the resistance, but the results are not satisfying.
Is there anyone who tested this king of a simulation?
Thanks.

Hi,
It sounds like your approach is OK. Can you describe (or show) your setup vs real life and also detail what is not satisfying about the results?
Thanks!
Jon
Sure, can you post it here?
Please also provide some details about what you are seeing from CFD vs what you are expecting to see.
Many thanks,
Jon
I am recently trying to simulate an industrial heater which is Accorroni Mec C 35 and i am also sending its specs. That is a school project of a friend of mine and i know that the product have some over heating problems so firstly i am trying to simulate the ral product then i wish to make some upgrades on the design.
And my problem is on analysis i am reading unrealistic temperature values like 1*E6 C. after some mesh independent analyses results did not change.
Thanks
Hi,
This is a pretty good setup to start with, nearly there I think.
A few things though:
I hope that helps,
Jon
