← ScienceWhich instability arises when Reynolds number exceeds limit in a microfluidic chip?
A)Turbulent flow regime transition✓
B)Laminar mixing enhancement occurs
C)Reduced interfacial surface tension
D)Increased dielectrophoretic particle trapping
💡 Explanation
Transition to turbulence occurs because increased Reynolds number signifies inertial forces dominate, leading to destabilization through shear layers; therefore, the transition to turbulent flow occurs, rather than stabilized laminar flow, because viscosity decreases with respect to momentum.
