Hi all,
I'd like to simulate flow over an airfoil at Rey 120,000. From the literature I understand that the flow has both laminar and turbulent portions, therefore a transition model may be the most reliable option in CFX. How can I use the Gamma Theta's intermittency factor for this purpose? The documentation says it is a measure of the probability that a point lies in the turbulent region. What does this mean practically and what information do I need to set it reasonably? I can make some prediction using XFOIL regarding the transition point. Thanks for your attention. Nick |
