Hi,
I am trying to simulate the airflow around an airfoil with high angle of attack using LES in FLUENT. However, I am not quite sure about what value of Cs constant should I put in. How can I calculate it, or at least what factors affect this Cs value? And while we are at it, it is my understanding that the Cs value is automatically calculated (and keeps changing) when the dynamic stress model is checked. Is this correct? And what are the pros and cons in using this dynamic model? Thank you in advance! |
