fluent nox module for nox reduction using sncr

asim ibrahim

hello every body i am modeling a combustion rig. i am using specie transport model and diffusion flame.

my major problem is related to fluent nox module. i want to simulate reduction of nox using SNCR. i did employ the fluent nox module and make the sncr option on but i didnot get the results as solution didnot proceed any further and fluent gives the message that " solution is converged". i also have difficulty in defining ammonia injection.

any body can give me some hint. plz help me waiting for mail thank you
