Which mechanism destabilizes an airfoil when airflow reaches Reynolds number threshold?

💡 Explanation

Laminar flow inherently cannot handle adverse pressure gradients, because the Reynolds number increase initiates turbulence. Flow separation occurs near the trailing edge, therefore lift dramatically decreases rather than friction increasing, due to the mechanism of adverse pressure gradient.
