← ScienceWhich mechanism initiates turbulent transition as Reynolds number increases?
A)Amplified energy transfer from boundary oscillations✓
B)Decreased fluid momentum diffusion process
C)Increased laminar viscosity dominates flow
D)Reduced impact because gravity stabilizes layers
💡 Explanation
Increased Reynolds number leads to instability; the Tollmien-Schlichting wave amplification causes turbulence because initially small boundary oscillations grow exponentially. These are amplified, therefore accelerating turbulence rather than stabilizing layer impacts because inertia dominates viscosity.
