I am doing a propane combustion simulation with fluent. Actually I am trying to reproduce literature results. My maximum temperature is 100K lower than literature results.
I am wondering is this because my case is not converged yet. all the residuals in my case are flat. The monitor variable kept constant as well. Then I checked mass balance of the combustor, it's balanced. Finally I checked the total sensible heat transfer rate. The detailed data set is as follows:
heat of reaction source:461.55 W
I know that the net heat transfer rate of the whole system should be 0 if the case is fully converged. However, I can not make it smaller with further iteration.
I am wondering is this an acceptable value to determine convergence or are there any ways to decrease this value further in order to get converged case.
