What different SST turbulent model between Fluent 12.1 and Fluent 6.3
 

Hello anyone
I wonder what different equation of k-omega SST between Fluent 12.1 and Fluent 6.3. I tried to compare these version for air mixing however both version give different result especially for high air velocity. Also, I wonder which one give accurate result?

Anybody have any idea?
