Posts: n/a
hi guys, I must simulate a combustion chamber of cylindrical shape to of over of which are placed eight burners I would want to study an eighth in order to save on the grid. Which conditions I must put to the sidewalls in order to make to understand to the fluent that the complete model is constituted from a cylinder?

Please help me!!!!!!!!!!!!!

If the burners are in separate chambers and if you are doing 3d study, then you can simulate with one burner and rest u can find with symmetry. But if there is 8 burners in a single cylindrical chamber, then in order to save grid, take 2D geometry. As in this case there is mixing effect also and you have to see the effect of all burners simultaneously.
