← ScienceWhich mechanism causes vortex shedding when Reynolds number increases?
A)Increased boundary layer kinetic energy
B)Decreased fluid dynamic streamlining
C)Elevated fluid momentum reduction
D)Increased turbulence induced separation✓
💡 Explanation
Increased Reynolds number indicates increased inertial forces relative to viscous forces. This promotes turbulence; therefore, increased turbulence induced separation causes alternating vortex shedding patterns rather than streamlined flow, because the Reynolds number increased to a turbulent boundary.
