← ScienceWhich outcome affects downstream mixing when fluid's Reynolds number exceeds a threshold?
A)Increased boundary layer separation length
B)Transition to turbulent flow regime✓
C)Elevated laminar sublayer heat conduction
D)Decreased pressure drop along channel
💡 Explanation
Turbulent flow regime leads to increased mixing, because above appropriate Reynolds numbers, inertial forces dominate via the Inertial Cascade mechanism, causing chaotic eddy formation; therefore, turbulent flows mix more efficiently, rather than remaining stratified like viscosity-dominant laminar flow.
