← ScienceWhich outcome results when designing high-speed underwater vehicle blades near cavitation limits?
A)Increased frictional drag on propeller face
B)Enhancement of laminar boundary layers
C)Suppression of tip vortex formation
D)Onset of turbulent flow regime✓
💡 Explanation
Onset of cavitation causes turbulent flow rather than laminar because bubble implosion introduces chaotic fluid motion via baroclinic torque. Therefore, turbulence increases rather than suppresses vortices or enhances laminar flow because the mechanism is related to collapse dynamics.
