Hi all,
I am doing a propane catalytic combustion with fluent. I set the under relaxation factor of energy to 0.9 and started iteration. After many iterations, I found the maximum combustion temperature just vibrated between 1600k and 2070K back and forth in just several iterations. It looks like the case is not steady. However, the profile of temperature is exactly the same with that in literature. I wonder why would this happen. How can I solve this problem. Best regards Weiqiang |
