detection of flow separation on airfoil
 
Hi,
I am simulating flow over a NACA 0018 airfoil at low Re numbers. I have regions on the airfoil with expressly low pressure( bottom of the scale)
Do they signify the separation bubble because I am still seeing pathlines through that region. I have tried simulating at moderate angles of attack so the aforementioned pressure areas cannot signify shock.
