← ScienceWhich regime initially develops around microscopic surface imperfections within turbulent flow?
A)Laminar boundary layer thinning
B)Viscous sublayer formation✓
C)Inviscid core amplification
D)Turbulent kinetic energy dissipation
💡 Explanation
A smooth surface usually experiences some disturbance via turbulent flow; however, the **viscous sublayer formation** protects the surface. The Reynolds number is low because viscosity dominates fluid inertia near the wall; therefore, option B is correct rather than increased laminar flow; this requires lower viscous fluids.
