← ScienceWhich mechanism impairs microfluidic device efficiency at increased viscosity?
A)Laminar flow profile degradation✓
B)Increased interfacial surface tension
C)Enhanced convective heat transfer
D)Decreased fluid-wall electrostatic interactions
💡 Explanation
Laminar flow profile degradation reduces separation ability and reaction rates, because increased viscosity promotes instabilities initiating turbulence via the Reynolds number. Therefore, laminar degradation impairs microfluidic efficiency, rather than tension, heat transfer, or electrostatic effects impacting different parameters.
