Heat flux question?
I'm modelling combustion in a rotary kiln using two-step eddy dissipation model in fluent. In order to calculate the correct wall temperatures I conducted a number of simulations to obtain the correct heat flux from the flame to the walls. This took quite sometime.
I now want to repeat the simulation but with preheated combustion air to determine its effect on the heat transfer inside the kiln.
My question is, can I use the heat flux profile obtained earlier on the baseline simulation, which does not have preheated air, or should I try and find the correct heat flux for the preheated air simulation too. I want to save time by not doing this but I'm not sure what effect this will have on the result?
