← ScienceWhich risk increases when supersonic airflow encounters bluff body?
A)Intense boundary layer transition to turbulence✓
B)Increased structural fatigue through creep
C)Elevated heat transfer by nucleate boiling
D)Higher electrical arcing from static discharge
💡 Explanation
Transition to turbulence appears following shock impingement onto the boundary causing flow instability. This mechanism results in increased drag because boundary layer mixing is magnified, therefore increasing aerodynamic drag rather transfer effects.
