I am doing the steckler experiment by using CFX. when i use the k-ε model, the central fire location is ok, but the result of corner location is quite different from the steckler experiment. i am quite sure my other setting is no problem.

My question is which model can i use except the k-ε model. Any other recommendation can give me.

thx

I had tried the k omega and SST model. The can't had a good resul. I tried the BSL renold stess, it gave a perfect result, but when i changed the door size, some door size cases were very bad. i dont know what happen.

recently, i tried the omega renold model, it gave the result is ok but not accuracy.

i had tried a hundred times in this experiment. what can i do to make it better.
