← ScienceWhich outcome occurs when a fluid exceeds laminar flow limits within a microfluidic device?
A)Increased mixing due to turbulence✓
B)Reduced viscosity near channel walls
C)Stable diffusion-limited transport regime
D)Decreased frictional losses in streamline
💡 Explanation
Increased mixing occurs because a transition to turbulence introduces chaotic advection, thereby rapidly increasing fluid interaction. Therefore enhanced mixing happens, rather than predictable diffusion, because inertial forces dominate over viscous forces causing disruptions to initially smooth flow.
