Which mechanism triggers turbulent flow when a fluid's Reynolds number exceeds a critical threshold in an aircraft wing's boundary layer?

💡 Explanation

Turbulence arises because when the Reynolds number limit is exceeded, inertial forces become dominant over viscous damping, leading to instabilities. This causes chaotic flow rather than laminar flow because, under stable conditions, viscosity would maintain order, and surface tension changes negligible effect.
