how to specify the transition in cascade?
 

I am modeling the Cascade T106 in fluent Cfx 12.0.16 usin the model "Transition SST" by Menter.
After my solution is converge, the contours show me the separation. I just want to know how to check where the flow is laminar and where the flow is turbulent? Does intermittency tell me anything or any other parameter?
please reply soon...
