← ScienceWhich outcome results when a microfluidic channel narrows significantly?
A)Flow transitions to laminar regime
B)Viscous forces dominate inertial forces✓
C)Cavitation risk in channel decreases
D)Fluid density variations get magnified
💡 Explanation
At small scales, a reduction in channel size dramatically lowers the Reynolds number; therefore viscous forces become greater than inertial forces because the Momentum Diffusion mechanism dampens turbulent effects rather than inertial instability dominating as in wider channels.
