Coal Combustion Separate Inlets
1 Attachment(s)
I am biting more than I can chew as a newbie. Basically I have the case of having a separate air inlet and a separate inlet for coal particles+nitrogen. Sketch is attached.
I have been reading around and I can't find any tutorials at all regarding coal combustion for fluent 13/14. Its a bit frustrating how there are lots of gas combustion cases but not a single one about coal combustion. Can anybody guide my as to which Species model is best? And if there are any items I have to be extra careful of? Any help would be greatly appreciated! Cheers! |
hai,
check out this tutorial. Fluent GUI is almost the same in 6.3 and 12 http://iceberg.shef.ac.uk/docs/fluen...f/tg/tut13.pdf regards, Byron Smith |
Thanks a lot for this!
Although I have quickly noticed that it just talks about having a single oxidizer stream (air). I was wondering how this could be done if there was another separate stream of just pure nitrogen. I've been trying to look at the settings in fluent to no avail. |

For both the inlets use all the species and for individual inlets give 1 as species mass fraction for O2 and the rest 0. same for the next inlet. hope this helps |
hey i am facing the same problem on how to define nitrogen inlet.... if you have solved the problem do help .... also what is jet-a<g> boundary species in non premixed combustion model in fluent.

Take note, this model is useful only when you have 10% by volume of solid fuel in the system. (or something like that anyway). The non-premixed model was used in the early days because it was computationally less intensive, but I'm pretty sure your computer should be able to easily handle species transport. |
