Dear all,
I have a problem with the turbulence model that I use in my simulation in ANSYS Fluent. I am trying to simulate the combustion of Air-Acid gas in a burner. Despite my inlets for Air and acid gas is uniform, I get antisymmetric flame (see the pic attached). I am using k-epsilon Realizable with standard wall function. Can someone help what the problem can be?
