Which flow regime develops when inertial forces dominate?

A)Full turbulence, high eddy diffusion
B)Laminar flow, minimal shear stress
C)Creeping flow, negligible inertia
D)Compressible flow, sonic shockwaves

💡 Explanation

High fluid velocity increases Reynolds number, driving turbulence. Therefore, momentum diffusion increases because chaotic fluctuations convert kinetic energy to turbulent kinetic energy, rather than sustaining laminar motion with viscous shear stresses.
