← ScienceWhich outcome is triggered when flow transitions above Reynolds limit?
A)Vortex shedding behind blunt objects✓
B)Reduced heat at frictional interfaces
C)Increased fluid density within chambers
D)Boundary layer remains predictably laminar
💡 Explanation
Vortex shedding begins above the the critical Reynolds number because inertial forces dominate viscous forces, leading to unstable flow oscillations; therefore vortices detach from an object, rather than consistent laminar flow.
