khaledhmz is an unknown quantity at this point

hello guys, I try to simulated a premixed swirl stabilized burner with two different turbulence model Realizable K epsilon and Standard k epsilon the problem it's not appear where Sn=0 and 0.35 but when I change the swirl number to Sn= 0.75 I fined a large difference between two model, and the flow structure changed (attached file) ...

I don't know why this difference Although the simulation of combustion is in the same swirl number...

can any one help me? ..I Am lost to try to find a solution for that

best regards
