Hello!
I am modelling gaseous combustion in fluent using Eddy dissipation and k-epsilon models. I have species profiles (CO,CO2,H2O,O2,CH4) at inlet which I implement using UDF. I am only modelling fluid domain but I want to reject heat from the fluid domain into surroundings (which is used for steam production). I want to remove 13MW of heat from walls and I am trying to use heat flux boundary condition at walls. But I get negative temperatures at walls when I put (negative heat flux) calculated by 13MW/wall surface area. There is enough heat available at outlet of geometry (54MW) which I can see from Flux reports. But I want the 13MW to be removed from walls, any help would be really appreciated. |
