← ScienceWhich outcome occurs when fluid flow's Reynolds number past a cylindrical support reaches a critical threshold?
A)Onset of vortex shedding appears✓
B)Dominant laminar flow is maintained
C)Fluid density approaches zero point
D)Peak fluid velocity plateaus sharply
💡 Explanation
Vortex shedding appears because above a critical Reynolds number the inertial forces dominate causing alternating vortices to shed. These repeating vortices affect the stability of the whole structure, therefore shedding begins, rather than laminar flow continuing.
