â ScienceWhich outcome occurs when calculating Reynolds number for aircraft wing design?
A)Flow transitions to turbulent; stallâ
B)Materials reach ultimate tensile strength
C)Engine efficiency exceeds theoretical limits
D)Lift exceeds the aircraftâs weight
đĄ Explanation
Airflow transition from laminar to turbulent flow, occurs because increased air velocity leads to a higher Reynolds number. This triggers boundary layer separation, an instance of flow separation phenomena; therefore stall occurs, rather than simply increased structural stress or performance.
