I have beening studying the coal combustion using ANSYS FLUENT. Its a swirl coal burner and I want to have a research about the relationship between the swirl intensity and unburn carbon. But I have a problem with the swirl blade and intensity. Maybe I have two clues. One is that making a complete geometry model and meshing it，but it is very difficlut; the other way is to mesh a modefied geometry but have to using the swirlling conditions to replace the blade. So the question comes？ How to set the swirlling boundary conditions when the swirlling intensity is konwn? I will appreciate any help form you!

Hey @anawana did you figure out how to simulate this? also of you have any source on where I can read about this type of situation that would be much appreciated. Thank you.
