← ScienceWhich consequence results when turbulence overwhelms laminar flow in a microfluidic mixing channel?
A)Decreased mixing efficiency occurs✓
B)Increased channel wall smoothness
C)Reduced pressure drop develops
D)Enhanced boundary layer stability
💡 Explanation
Decreased mixing results where turbulent eddies fail to penetrate all regions, because coherent structures form rather than small-scale diffusion. Thus, mixing efficiency drops rather than improving, unlike cases relying solely on diffusion, which the channel is designed to mitigate.
