← ScienceWhich outcome occurs when a liquid flowing through a microfluidic channel exceeds its critical Reynolds number?
A)Transition to turbulent flow regime✓
B)Formation of a stable laminar layer
C)Decrease in the fluid's dynamic viscosity
D)Increase in the effective channel diameter
💡 Explanation
The fluid transitions to turbulent flow because above a critical Reynolds number, inertial forces dominate; thus, random fluctuations lead to chaotic mixing. A turbulent regime occurs, rather than laminar because viscous forces can't suppress instabilities.
