← ScienceWhich risk increases within a microfluidic device exhibiting creeping flow?
A)Backflow through the microchannels increases.
B)Increased inertial forces cause turbulence.
C)Dispersion dominates, blurring fluids.✓
D)Fluid's density varies greatly through flow.
💡 Explanation
Dispersion increases because creeping flow features very low Reynolds numbers. Molecular Diffusion dominates, smearing fluid boundaries because inertial effects are minimized in the flow. Therefore, dispersion rises rather than turbulence occurring due to decreased inertial forces.
