← ScienceWhich outcome occurs when air passes through an aircraft's vortex generator?
A)Increased boundary layer kinetic energy✓
B)Decreased adverse pressure gradients
C)Laminar flow becomes fully established
D)Induced drag approaches zero asymptotically
💡 Explanation
Increased boundary layer kinetic energy results because vortex generators induce controlled turbulence, reinvigorating the slow-moving air. This mixes faster air with slower thereby preventing flow separation, therefore delaying stall rather than allowing laminar flow because that would quickly lead to separation.
