← ScienceWhich consequence results when transonic airflow encounters adverse pressure gradients?
A)Boundary layer flow reversal occurs✓
B)Lift-induced drag substantially decreases
C)Laminar flow definitively transitions
D)Aerodynamic heating uniformly reduces
💡 Explanation
Flow reversal occurs because separation becomes dominant due to increased adverse pressure, triggering turbulent flow, increasing momentum near the wall through the mechanism of momentum diffusion; therefore, separation will occur, rather than improved aerodynamic heating because compressibility effects dominate.
