If an airfoil is inclined at a high incidence angle to the flow, then the boundary layer will tend to separate from the top surface and a large wake is formed downstream. Such a separated flow is a characteristic of a flow-field over a ____ airfoil.

Explanation:

A separated flow is a characteristic of a flow-field over a __Stalled__ airfoil. Stall is the reduction in lift coefficient generated by a foil as angle of attack increases.

The critical angle of attack is typically about 15 degrees, but it may vary significantly depending on the fluid, foil, and Reynolds number.The boundary layer will tend to separate from the top surface and a large wake is formed downstream.
