Internal field temperature decreases after each iteration (Combustion Modeling)
I have a very general question:
I try to simulate combustion. LES, non-premixed, one inlet for air (to stabilise the flame) and another one for fuel (300 K at both inlets and at other BCs), orthogonal simple mesh, no radiation model, no walls....a veery simple case.
The temperature (internal field) decreases at each iteration and this non-physical annoying phenomena depends on the velocity (high inlet velocities → temperature decreases faster). The flame temperature seems to be OK.
I am sure that there are several and very simple explanations for this problem. Can someone tell me a little bit about this?
Well.....with BCs I mean just boundaries....sorry
